OptiStruct Application In Design of Vehicle Front-end Module Bracket

Li Mingzhe   Qiu Zhixue

Abstract: This paper discusses the application of optimization software Altair OptiStruct in design of vehicle front-end module bracket which uses the whole plastic or composite materials. OptiStruct is quite useful in design and weight reduction, and gives the exact parameters for front-end module bracket. While the weight of the bracket reducing, the safety and economy are enhanced. Some of the brackets with composite materials use the stamping parts for connection, OptiStruct could be used for the topography optimization, as a result, the stiffness of the structure could be improved.
