Abstract

The accuracy of simulation for automotive structure is increasing more and more. However, it is difficult to find out a few good design variables under a mass constrain, since there are tremendous design variable candidates in a large-scale Finite Element model. Therefore we have to select some effective parts as design variables before solving an optimization problem. In this paper we propose a new basic concept of contribution analysis for minimizing a target response using mutual mean compliance. First, we present how to calculate a contribution rate to a static target response after clarifying the difference between elastic strain energy and mutual mean compliance. Secondly, we expand the above method to a dynamic problem. Then, the dynamic contribution rate is divided into 3 components, which are mass, damping and stiffness ones. Finally, we demonstrate the proposed method using a cantilever model.
