Overview on Innovation of Topology Optimization in Vehicle CAE

This paper based on various vehicle model structure components, introduce on the general flow of structure topology optimization design, and reported on the latest application and innovation of the related representative software, including the development of CAE integrity software system. Overview on the innovation of application research of components property optimization and reduction of body skeleton and parts weight. The practice application demonstrated the significance of using finite element method for topology optimization of mechanical support structure, provides an important reference on conceptual design for mechanical structure and mechanical components lightweight design, and undertaken a forward-looking work on the development direction, the scope and trend of application and key technology of structural topology optimization.
