| Abstract: | Four motor hood structures of different materials are designed by taking lightweight material characteristics,technique of production and connection into consideration.After topology optimization these structures are analyzed and estimated by the finite element analysis(FEA) simulation results.The carbon fiber reinforced plastic(CFRP) structure, whose performance is the best among the four structures,is chosen for trial-producing and testing.The superior performance of CFRP structure is validated by a comparison study of test results and simulation results.In this paper the technical route of lightweight for car body components is discussed in the aspects of the lightweight method,design and test specification,material selection and structure design. |
