Topology optimization design of the bracket of a special vehicle based on FEA method

In allusion to a certain kind of bracket of work cabin overhead support equipment components of the special vehicle, taking OptiStruct software as optimization design platform, the topology optimization of the bracket is carried out by using variable density method. The geometry model of the bracket is rebuilt and the finite element analysis of the bracket is carried out, then the stress and deformation of before and after optimization are compared. The results show that the topology optimization method is an effective optimization method to carry out topology optimization of mechanical loading structure with FEA method. The model and approach adopted in this paper provide an important design reference to the mechanical structure and components lightweighting design.
