In order to reduce the weight of the bracket and improve support capabilities,and realize lightweight design.Using the homoge-nization method,a theoretical model of topology optimization is established with the cell density of the microstructure as the design vari-able,the volume function as the constraint function,and the minimum compliance as the objective function.and topology optimization de-sign of bracket by finite element analysis software of ansysworkbench.According to the optimization results,the structural improvement and static analysis of the bracket are carried out The analysis shows that under the condition that the bracket bears the same load and meets the strength and stiffness of the bracket,its mass reduced by 41.4%,which achieves the purpose of lightweight design of the structure.It's con-clusion that this has the engineering application value for the bracket improvement design,and also provides a reference for the lightweight design of similar product structures.
