In accordance with the regulations GB11567-2017 “Requirements for the Side and Rear Lower Protection of Vehicles and Trailers” and the lightweight requirements of the frame, the development indicators are defined, and the rear protection layout plan is confirmed through benchmarking analysis. Based on OptiStruct, the topology optimization design of aluminum profile beam and casting installation bracket is carried out to determine the conceptual model, and the detailed structure model of beam, installation bracket and transition bracket is determined according to the bending section coefficient and weight index. Based on the ABAQUS elastoplastic analysis method, the static simulation analysis of the detailed structure of the rear protection is carried out. At the same time, the bench test verification is completed. The results meet the requirements of the regulations, which proves the correctness of the optimization design and analysis method of the rear protection structure.
