Impact test simulation and structural optimization of aluminum alloy A356.2 wheel hub

Abstract

In order to improve the design efficiency of automobile hub, finite element simulation analysis is performed on the impact test of automobile hub. According to the national standard of impact test, Ansys Workbench software is used to load and constrain the explicit dynamics elastoplastic model. According to the results of impact strength analysis, the deficiency of the structure is studied, and put forward the corresponding structural optimization design. The actual test verifies the accuracy of the impact test simulation. Ansys software is used again to analyse the impact stress of the improved wheel hub to verify the rationality of the improved structure. The experimental results show that the method of dynamic analysis is practical and effective in calculating the stress and strain of automobile hub impact test. The research results provide theoretical basis and practical significance for the design and development of automotive aluminum alloy wheels.
