Research on lightweight design of automobile hub based on OptiStruct
Based on the finite element analysis method and the topology optimization theory,the lightweight design of a vehicle hub structure was studied,and the lightweight hub schemes under different constraints were proposed and compared.Firstly,the initial hub structure was designed according to the existing vehicle data,and the service strength of the original model was checked based on the typical operating conditions of the vehicle.Then,the lightweight scheme under different process constraints and volume constraints was studied by combining the topology optimization method,and the feasibility and rationality of the optimization design scheme was investigated,which provided a certain reference basis for the lightweight design of the hub structure.
