Abstract

The finite element method is, alongside with CAD, one of the most
efficient tools for optimizing the quality of engineering tasks (Klein
2010). Furthermore, the currently available FE software is getting more
and more user friendly. However, especially less experienced users -
such as designers - perform more and more FE simulations but do not
have the knowledge of experienced computation engineers. Often these
users do not have a complete overview of the performance of currently
used simulation and calculation tools for securing product and also
manufacturing process characteristics. However it is highly essential to
optimize the quality and minimize the costs of a technical design as
early as possible during the product development process. Therefore,
these users need to be assisted when performing simulation tasks. This
can be achieved by an integrated plausibility check in the postprocessing
of the FE software. When an existing FE result data set is
checked for plausibility further steps towards a better assistance for part
time users can be taken. Such as an error assistant for implausible
results or a context-sensitive result visualization to help the user to
understand the simulated results.
The presented approach in this paper is part of the Bavarian Research
Cooperation FORPRO² for efficient product and process development
by knowledge based simulation. The aim of the Research Cooperation
is to increase efficiency of virtual product and process development
through the creation of an expert knowledge based simulation
framework for property optimization and quality improvement of new
products. The expected result is to provide the necessary situational
simulation knowledge as a function of decisive factors such as the
phase in the development process, the manufacturing processes
employed, and the company's individual circumstances. Within the
Research Cooperation an FEA-assistance system with an integrated
plausibility check is developed. In this paper an approach for plausibility
checks applicable for different standard components with mathematical
meta-models is presented. At first the terms plausibility, verification and
validation are distinguished. Then different meta-models and their
requirements and possibilities for evaluating the quality are shown. The
paper closes with an exemplary application – a piston pin of a combustion engine, for which a plausibility check with different mathematical meta-models is demonstrated.
