Does anyone have any experience with designing and manufacturing bespoke hand-arm measurement adaptors for vibration measurement?  I've been constructing 3D printed ABS prototypes based upon dimensions from BS EN ISO 5349 Part 1 & 2.  However, I'm struggling to find any good examples of bespoke devices being constructed and tested prior to utilisation.  I'm attempting to build a bicycle grip mount that incorporates an Adafruit LIS3DH accelerometer break-out board and I2C bus cables. 
Relevant answer
Answer
I'm looking into building a vibration logger that can be mounted on a bicycle handlebar (my interest is in comparing the vibration transmission differences between bicycle front forks made of steel with a curve, vs straight forks made of other materials.
My current focus is on using an Arduino nano 33 IoT board as it includes an accelerometer and will run off a couple of coin cells. This would communicate via BLE with another device which would store the accelerometer data as it's being transmitted.
Any updates on your work?

Based on my experience, to start a lean culture in a leanness organization it all starts with the senior management and leadership team engagement. It is not something to be delegated to human resources area, and it is not only about outsourcing consultants. However, when the implementation phase is complete, the kick-off phase begins. This said, in your understanding what are the top lean culture implementation challenges to be addressed by a leanness enterprise?
Relevant answer
Answer
Hi There Leandro,
I am curruntly implementing lean manufacturing systems and tools. I have found that one fo the biggest challeneges is adherence to the lean systems and tools.
I have overcome this through effective communication and by implementing recognition process. This shows everyone how well they are doing against over areas and identifies the areas performing the best.

During planning phase of product life cycle, designers usually encounter various bottlenecks and decision making dilemmas. what are those.
Relevant answer
Answer
There are several. Which of those is most important will depend on sector and specific business, I guess. Just listing a few:
First, there are trade-offs. Between environmental and economical aspects (e.g. more sustainable material, but more expensive), but also between different environmental (or social) aspects (e.g. less/non toxic material, but requires more of it, or higher embodied energy).
Second, there are typical business consideration related to innovation: lock-in effects of major investments / switching to new (at least new to firm) technology and partners / becoming reliant on single supplier of sustainable material etc.
Third, there are internal organisational issues. Overcoming resistance to change in your organisation.
Fourth, external factors. Legislation may prohibit the best solution or force a focus on aspects that are actually of lesser concern for your industry/product. Other partners in the value chain may have more power than you and resist or push for alternative directions.
Perhaps your question was aimed at one particular of these types of dilemma's (or yet another)?

Life Cycle Analysis plays significant role in many research proposals and is one of the main significant criteria that exist during the evaluation process. It’s mainly used (beside others) to calculate the carbon footprint of several operations and or several procedures. However, remain unclear if a complete and detailed LCA can be done, in order to compare with the state of the art. In addition, this because systems boundaries can change all the time. What is your opinion?
Relevant answer
Answer
It depends on your target. Comparative LCAs work very well. Establishing an environmental impact analysis for the life of a product is a different animal. LCA impact categories hide details. The methodology of the LCA, the approach, and the standardized impact categories, data bases are pretty useful.
I prefer to work with raw data, have the process map, analyze all emissions and impacts one by one, or choose the significant ones as indicators. For climate change impact I vot for using emission calculations instead of LCA.

Hello everyone, i'm an intern in a company that produces HVAC systems, my mission is to study the transmission of the vibrations generated by the moving parts(fans, compressor...) to the bodycar, so this company didn't buy yet a licence for a FEA software like ansys or abaqus, the problem is that my tutor don't have any knowledge on finit elements analysis, so every time i talk to him about FEM it's like I'm talking in chineese. So in order to get me busy he asked me to do some studies about the vibrations of the HVAC WITHOUT A FEA SOFTWARE, and to be honest with you, i don't have any idea from where to start, i tried to simplify the system into mass spring and dumper and slove the deff equations of the system but i don't have any information about the natural frequencies of the HVAC nor what should be simplified,
thanks .
Relevant answer
Answer
You can use SCILAB (developed by INRA) which is a free soft with a module for simulation of dynamic systems (XCOS). A VERY low cost soft for FEA is LISA which is free for up to 1400 nodes and does cost less $100 for nolimit number. Support is very efficient. Both are easy to use.
Now you mention 24 own frequencies, I presume that amplitudes are very different  I would first concentrate on major frequencies and see what would be the influences of other frequencies on the system.
Which are the sources for the 24 frequencies ?

Official JCR impact factor listing needs subscription. Usually universities provide access to listing. For finding some possible related journal, any of the impact factor journal in major databases will be having clearly quoted impact factor for JCR 2015 at their site. Just go through official website of renowned publishers only. Like elsevier, emeral, taylor & francis, Wiley etc. Don't trust twisted words at unknown journals/publishers website for that. If you need to check real impact factor status of a journal, you may ask someone who has access to JCR to verify if the journal is actually listed there or not. All the best. :)

ISO 13399 turning database of Sandvik Coromant
Relevant answer
Answer
Dear Daniel Martinez Krahmer,
Thank you. Their is a detailed methodology for selecting a tool according to Sandvik, for example, the operation affects the selection of insert and holder, the insert point angle is selected according to the geometry of the  part, for example a recess feature needs a good tool to avoid part collision, the grade of insert is selected according to the geometry of insert (for example the geometry PR = roughing steels).
The problem is not here. The problem is the new iso13399 and cutting tool selection.

In step-stress acceleration life testing. How can I compare between two different models and two different distributions ?
Relevant answer
Answer
Assalam Alikum Abd El-Raheem,
I do not think Step-stress ALT will use different methods than other models like regression models. In general you need to do some diagnostics for the residuals and check some tests of fit like F test. you can also compare models by using some criteria such as MSE or any other loss function.

In human factors and ergonomics, for example, identified trends include usability, universal design, user-centered design, collaborative design, trans-cultural design, customer-centered design and experience-based design. Within these trends / categories many methods can be classified.
Relevant answer
Answer
Sure. You can look at this from a chronological perspective as well as a philosophical perspective. The challenge is that many of the terms used never had solid definitions, i.e. not everybody meaning the same thing used the same term, and not everybody using the same term meant the same thing. However, you could say that in design there was first a development to focus on environmental aspects dominantly (up to mid 1990s), an approach often termed 'design for environment'. Next step was to balance environment with economic considerations, often termed ecodesign. Next step was also including social issues (roughly from 2000 on-wards) resulting in 'Design for sustainability'. All three are basically resulting from an ideal to 'do more with less', i.e. eco-efficiency, which was the industry response to the Brundtland definition of sustainable development. Parallel to the eco-efficiency development there were different philosophical developments, such as the natural step, cradle-to-cradle and biomimicry. At the moment the momentum seems to be with 'circular economy' which aims to combine many of these earlier approaches and insights.
