Plastic Part Design for Injection Molding and Additive Manufacturing

NVH (Noise Vibration Harshness) characteristics of components for automotive lightweight de-sign are increasingly becoming the focus of the development of OEMs and suppliers. Although noise has been greatly reduced by using sound-absorbing materials and using electric drivetrains, passengers are being increasingly scrutinous when perceiving vehicul...

Das akustische Verhalten von Bauteilen für den automobilen Leichtbau steht zunehmend im Vordergrund der Entwicklungsaktivitäten von OEM und Zulieferer. Geräusche im Fahrzeug sind durch schalldämpfende Materialien und durch den Einsatz von Elektroantrieben stark reduziert worden, wodurch Störgeräusche von den Insassen verstärkt wahrgenommen werden....

This MATLAB code optimizes Prony parameters for FE-simulation which are generated from DMA measurements of viscoelastic polymer material. This MATLAB code is used to determine the parameters of an extended Maxwell model (Prony equation). It optimizes the Prony parameters n, gi and ki considering the best fit for the curves of G´(ω), G´´(ω) and tan...

Durchgeführte Untersuchungen und Ergebnisse der Dissertation ”Untersuchungen zur akustischen Formteilauslegung”

Vorstellung einer integrierten Simulationsmethode für die akustische Formteilauslegung mit der Simulationssoftware Moldflow, Digimat, Abaqus und Actran

NVH characteristics of injection-moulded thermoplastic parts, e.g. interior components for vehicles, can be influenced in structure-borne sound transmission by changing the material itself and its microstructure orientation used in component production. In order to reduce the costs and efforts of sampling different materials and conducting tests, t...

Manufacturing Methods for Tool and Mold Making

Nowadays a future oriented product development and design of capital goods should consider a design for recycling and maintenance. So new practical design strategies and methods are needed Tn this raper there is given a method-oriented basis for the development of practical and flexible design strategies and methods for the design for recycling and...

Doktorandenkolloquium zur Kreislaufwirtschaft und Demontage an der TU Berlin, SFB 281

A prerequisite for a both economically and ecologically adequate circulation of products is to give products in the development phase a configuration to make them suitable for recycling. On the basis of product analyses oriented on recycling and by making use of computerassisted systems for the evaluation of disassembly, rules of configuration will...
