Modular Car Body Design and Optimization by an Implicit Parameterization Technique via SFE CONCEPT

This paper presents recent developments on implicit parameterization techniques (based on the software SFE CONCEPT) for shape optimization of vehicles in the context of modern modular car body design. Because of the implicit definition of the parameters complemented by the mapping and re-meshing techniques inherent to the software, a flexible and powerful optimization approach can be realized, where the connectivity is maintained, the accuracy of finite element computations assured and the efficiency improved via appropriate definition of design variables and optimization algorithms. This is first demonstrated on component and module level and finally confirmed by a full vehicle problem.
