Structural Optimization Design of Polydicyclopentadiene Bonnet

Abstract:

Taking the engine cover of a passenger car as an example， the structure optimization design method flow of Polydicyclopentadiene （PDCPD） engine cover was established to realize the lightweight structure design. The material property data of PDCPD were measured in the experiment， and the design process of equal stiffness and equal strength calculation-topology optimization- morphology optimization?multi-objective parameter optimization was applied to the structural optimization design under various working conditions. The performance analysis results show that compared with the original steel engine cover， the PDCPD engine cover designed by this method can achieve significant mechanical performance improvement， and the lightweight effect is obvious.
