- Abstract
- This paper presents topology optimization problem for the load-path development of an automotive body. Conventional topology optimization problem minimizes the weighted compliance in case of a lot of load cases. Unless boundary conditions of load cases are different, conventional optimization problem cannot consider the effectiveness of load cases without discrimination. To improve this problem, the optimization problem is proposed to minimizes compliance of each load case and find the maximum density distribution. Topology optimization is performed on BIW model consist of hexahedral elements and new load-path is appeared.
