Abstract

To remain competitive in global markets most product development processes are conducted by computer-aided tools (CAx-tools) to accelerate product design. But because of missing simulation strategies and procedure guidelines the development process is constricted and hence slowed down. Main topic of article is to show a methodical approach to handle complex processes supported by computer-aided tools. By detailed analysis of these programs, their functionalities and complex interactions can be disclosed. Product development as a whole consists of many sub-processes that have to be performed in specific orders, iterations and linked to certain product-specific data. Depending on their relations single sub-processes can be composed to complete process-chains as this contribution will explain.
In the second part of this article, this procedure, supplying the developer on different process levels and steps, is to be shown by means of a practical example of product design, the elastomer damping elements of claw couplings. The usage of polymers has successfully been established even in high performance fields. But application in these areas assumes correct dimensioning of the polymer part. It is possible to predict material behaviour by computer-aided tools, such as finite element analysis. Nonlinear material properties can be mapped and scaled to a computer model by skilled combination of virtual product design and prototype testing using the method presented.
