Automotive - Science topic

I want to download BioClim data containing the Generic grid format (bill) to use in species distribution modeling

Can we use metal matrix composites ( Al alloy + glass fiber reinforcement) for automotive components? What type of casting process will be used to manufacture a part using this material for the bulk production perspective? What are the advantages / disadvantages of that method compared to LPDC / HPDC?

Which are the reinforcement we can use , other than glass fiber ( from the weight reduction perspective)?

There are a number of driving cycles and scenes (acceleration, hill-climbing, etc.) to be considered for vehicle design, including legislative requirements and each OEM's own design standards. Taking all the design trade-offs in terms of the cycles and scenes into consideration would be almost impossible and computationally intractable for example even in the case of design optimization. I am wondering how people manage it. Do they only focus on the cycles and scenes that are important for marketing purposes to determine the vehicle baseline design?

Looking for some good resources for automotive radars. Please suggest good ones.

Is the use of non salient pole PMSMs a good idea in automotive traction applications?

What are the issues to be encountred when flux-weakening of PMSM at large speed intervals?

Can anyone share the details about Brake wire brush noise ?

How the test has to be conducted to capture the wire brush noise, frequency range etc., ?

I need to find a proper method to prepare sample solution by digestion for Pt-Pd-Rh elements from spent automotive catalysts. Any suggestion except application of microwave-assisted digestion would help me.

Looking for alternative MIMO based automotive radars other than TI make with low cost and yet provide good performance.

I am looking for low cost radar sensors, which can detect targets up to 150 m in range, while simultaneously providing good range, velocity and angular resolutions.

We have collected some data from a automotive radar sensor and a camera sensor simultaneously, and we wish to fuse the track data from both these sensors. Could any one provide the methods, approaches and techniques pertaining to this important problem and any sample codes that are available. That would help us significantly.

Dear colleagues,

Dear Community,

since UTAUT2 has already been discussed here several times, I can imagine that my concern also affects other people.

I use the addressed model to find out which factors influence the adoption of a certain product. Using the AMOS 28 program, I run a measurment model (CFA) and a structural model to evaluate a model fit.

The measures TLI, CFI, GFI are minimally too low. Would you have a strategy for me on how to move the values more towards a model fit? I have already tried to remove the question items with low factor loadings without much effect.

I hope that the attached screenshots can give helpful information. Among the screenshots you can find the conceptualized model, the results of measurement model and the cut-off values as they were defined.

If needed I am happy to provide you with more information.

In advance, thank you for your great assistance.

If load is increased in a diesel engine running with diesel do HC & CO emissions increase or decrease?

Points: 1. If load is increased more fuel is supplied which increases HC & CO.

On the controversy If load is increased cylinder liner temperature increases which reduces the HC & CO emissions. whether both are correct or not. kindly suggest. whether units of measurement matters.

Will the technologies of electric motors and the new generation of batteries installed in cars and other motor vehicles be developed in the scope of the main directions of development of electromobility of the automotive industry? Will the technology of hydrogen engines or other types of engines be developed as part of the development of eco-motorisation? At present, in the majority of countries, there is no financial resources for financing high-budget pro-ecological projects from public finance funds? Should new, new ecological innovations, new technological solutions in the field of renewable energy sources, new ecoelectrodes producing electricity for the needs of electromobility in the automotive industry, new generations of batteries, photovoltaic panels, energy storage and transmission stations, hydrogen and other engines, etc. be created that the production and use of electricity generated from renewable energy sources becomes profitable, that it becomes a profitable business, that electromobility will become more and more profitable, profitable, and the prices of electric cars drop significantly? If this process lasts for a long time, there may be a shortage of time to implement the necessary reforms aimed at disseminating in the global economy a model of sustainable pro-ecological development based on the concept of green economy. If this process lasts much longer than by 2030, there may not be enough time to carry out the necessary reforms to reduce greenhouse gas emissions and, consequently, the planet's warming process will accelerate considerably, this process will be irreversible and will continue to accelerate and towards the end of the 21st century will lead to a global climate disaster that threatens the life of all humanity and most other forms of life on Earth.

In view of the above, the current question is: What are the main directions of the development of electromobility of the automotive industry?

Please, answer, comments. I invite you to the discussion.

A. Global semiconductor chip shortage

B. Government regulation of internal combustion engine powered vehicles

C. Disruption from digital start-ups

D. Trade tensions between USA & China

E. Lasting economic impact left from Covid-19

F. Other (please comment)

How can we use all the three domains of Blooms Taxonomy to give feedback to them on area that he/she should focus on?

Are you aware about some software that can do this?

Thanks.

Is it only when the production of electric cars will multiply, popularize and be bigger than cars powered by an internal combustion engine, then only will the price of an electric car fall below those versions that are powered by traditional technology of burning minerals? Do other factors also determine this?

More and more car companies are introducing versions of some models of produced electrically powered cars into production, ie they are becoming part of the increasingly global trend of electromobility. However, electric cars are still much more expensive than those powered by an internal combustion engine. In some countries, the state pays a significant part of the purchase of an electric car.

An interesting issue is that pro-ecological technologies have been known for a long time but have not been introduced to mass production. When the production of cars started at the end of the 19th century and at the beginning of the 20th century, then electrically powered specimens appeared at that time, but mass production was not developed as part of the development of electromobility, but this method of power supply was replaced with internal combustion engines. Unfortunately, it took 100 years to finally take the issue of electromobility seriously.

In view of the above, I am asking you the following question:

Please reply

I invite you to the discussion

Thank you very much

Best wishes

We may have positive or negative impact on material purchasing, like if we replace the existing raw materials (which are responsible for co2 emissions during production in automotive industry) with a renewable raw material(like wood) which is also an eco friendly one. How this approach can affect the process of material purchasing in automotive industry.

Hi everyone, in the sequel of the previous discussion for Artificial Intelligence Scenarios on Automotive Dealer where you helped a lot find out some useful scenarios, now it's the time to discuss how we can take the advantage of association rules. I am searching for possible applications in the Automotive Business.

Below there is a simple example of a basic scenario that I have discovered already and I would like to enhance it or discover new ones, that could help Automotive Industries on taking proper business actions:

1. Based on labor and item relations that are produced through each service basket (invoice) you can manage your shelves, shelves that containing items that are used frequently together need to be close, or labors/items that are used frequently together need to be in the area of specific labor type, or make promotions that can result in an increase of sales.

What do you think?

Hi everyone, lately by using all the nice tools and benefits that Artificial Intelligence can offer as a technology, I am searching for possible applications in the Automotive Business.

Below are some simple examples of basic scenarios that I have discovered already and I would like to enhance them or discover new ones, that could help Automotive Industries on taking proper business actions:

1. Based on historical CRM Opportunities taking into account the Lead Source (TV, WEB, Phone), Customer Genre, Customer Age, Customer Geographical Area, Customer Follow-Up-Times and Model Of Interest, Model Price, predict the possibility to convert this opportunity into an Invoice.

2. Based on historical Service Document Turnover (Service Quote -> Service Schedule -> Service Order -> Service Invoice), predict the possibility of a new open (un-invoiced) Document.

3. Based on historical Vehicle Document Turnover (Vehicle Quote -> Vehicle Order -> Vehicle Invoice), predict the possibility of a new open (un-invoiced) Document.

4. Based on historical clocking of technicians that spent on fixing vehicles taking into account Model Code, Vehicle Mileage, Job Qualification Code, Parts Number Labor, Number, predict the expected workshop load for the following scheduled based on open Service Schedules.

Quick question I couldn't easily find a definite answer, so I hope someone here could help. I've been looking for information about the ratio (by weight) of glass or carbon fiber to epoxy matrix in composites that are used in automotive applications. The info I've found suggests that 60% fibre/40% epoxy matrix seems to be common for glass fibre reinforced plastics (GFRP), but does this apply in automotive applications, and is it representative for carbon fibre reinforced plastics (CFRP) as well?

I am doing the mathematical modelling of a heavy vehicle for analysis of its roll handling behavior. I need to know the method of calculating the roll center of the vehicle, both using some software tool and experimentally. Any information about this will be appreciable.

Hello,

I am doing a metal forming simulation in Abaqus, and I want to create a mesh similar to the one in the attached image. Particularly, on the "Blank" part, where there is a dissimilar mesh transition, going from fine to coarse.

I heard that if I use TIE constraints then this will work. But it is not clear to me how to do this?

How could I use TIE constrains in Abaqus to create and merge dissimilar regions of mesh density within a part?

Many thanks!

In most of literature and thesis, the application mentioned like the material is well suited for the ​aerospace, automotive and similar structural applications.

what are particular applicability area of the developed material and what extent?

A look at the current literature suggets only a handful of work being done on Usibor 1500 to Al 5XXX/6XXX alloy welding. The results available also indicate poor mechanical properties.

Why is welding of Ultra high-strength steels like Usibor 1500 to automotive grade Al alloys so difficult. Any comments would be useful.

I am looking for aerogel applications, properties and also environmental impact (fuel consumption, emissions, etc) in the automotive industry, especially in the high performance field.

Dear Fellow,

We all know about Q1 and Q2 based journals in the area of robotics, automotive and transportation. Can you give some name of conferences based on the said criteria?

Thank you, Indeed.

Here I am gonna ask a really stupid question, but I don't accept stupid answers.

These days, I got chances to "play" with some automotive radar PCB (not assembled one, I do not have the chip's information), but I wanna know what is what on the PCB.

Normally I take the most array number one is LRR Tx, since higher the gain longer the range, then take next to him as SRR Tx, since they are from the same area (chip area, transmitter?), then take others as receivers, usually four of them.

But on some boards, they are all from the same transceiver area.

My question is that 1. normally how many LRR Tx, SRR Tx and how many receiving antennas on the board?

My another question is that 2. I heard 76-77GHz is for LRR-Tx, 77-81GHz is for SRR-Tx. Is it correct? and the Rx is 76-81? why don't we use LRR-Rx (76-77GHz), and SRR-Rx (77-81GHz) separately?

What are the various Nanocomposites used in Automotive Application ?

I am about to visit wind tunnel facilities to test an automotive vehicle. The speed at which the CFD analysis are being carried out is 17 m/s To avoid the blockage effect a scaled model will be created with a scale of 1:3. I am assuming that in order to achieve the kinematic similarity the Reynolds number must be the same. Hence, the speed must be 3 times greater than the speed of CFD simulations. I have assumed that the forces acting on the car will be given by the equation RealForces =(1/scale^2)*ModelForces.

These forces will be the forces for the real car running at three times the speed?How can I calculate the forces acting on the real car at 17m/s??

I am writing my thesis on sustainability performance of the automotive manufacturing companies and this is one of the empirical questions of my research.

Hello,

I would like to get an idea about the usual thickness values of coatings in high strength and advanced high strength steels (e.g. JAC590/980, USIBOR 1500 etc.) used commonly in automotive industries.

Any insights would be appreciated.

I am working on vibration test.

my question is how much 'g' level can we accept for a automotive components when it is subjected to forced vibration in terms of 10-40 'g' at various frequencies range of -0-2000 Hz.

eg: input is 10g at 500 Hz, and output vibration level is 200 g at 500 Hz , Is it accepted or on what basis can we have any criteria?

I know that in some years SAE Level 5 Autonomous Cars will be sold in the market, but probably just as concept cars. When do you think they will become a competitive solution in the market at affordable price?

Since the efficiency of a gas turbine declines almost exponentially with respect to the load, and the gas turbine works best at its maximum load, Will be possible a gas turbine, perhaps electronically controlled to improve efficiency at low loads for automotive applications?

I´m currently working on my bachelor thesis about the usage of Sequential Pattern / Sequential Rule Mining-techniques for automotive predicitve maintenance.

– >I want to answer my research question what amount of data is necessary to extract meaningful / significant Sequential patterns / rules in a sequential database.

I don´t have access to real-life automotive predictive maintenance data, so i thought about taking an webpage click-stream dataset. So my consideration is to take an sequential dataset and then gradually minimize it.

Let‘s assume that with an dataset of 1000 sequences it´s possible to extract 50 sequential rules with confidence 0,8, and with half of the data (500 sequences) it´s only able to extract 35 rules with confidence 0,8, with 50 sequences only 10 rules, and so on. I think i will only change size and variability of the data set.

Do I think correctly or are my thoughts wrong?

I would very appreciate any answer,

Could anyone who can recommend me some info about the open source tool which can simulate practical scenarios for the usage of visible light communications (VLC) in indoor positioning system ?

I am writing my thesis on sustainability performance of the automotive manufacturing companies and this is one of the empirical questions of my research.

Originally, I wanted to use random stratified sampling for my survey involving an automotive industry. The sample is based on the value chain comprising of manufacturing, sales, quality finance and HR. The composition of the respondents follows the percentage breakdown of the population. I did not have problems with sampling during the pilot but during the main survey, there were a number of organizational changes that resulting in poor response from the sales division with only less than 5 respondents out of a target 150 respondents. What should I do? I am consideringremoving the sales division and focusing on the balance and considering focusing the study on the supply chain. Alternatively, could I use all respondents minus sales but still consider the survey to be on the automotive industry? Any other suggestions?

someone who works on the design and implementation of data backup of automotive sensors?

Dear Researchers,

I do research in the domain of electric vehicle testbeds. Therefore i am interested in already existing ontologies in the automotive domain. If you know good scientific books and papers giving a deep insight in the domain it would also help a lot.
