| Abstract: | The finite element model of tractor frame was set up and the statics analysis on multiple working conditions was carried out.The solving method in engineering application was presented for the common problems on multiple working conditioned topological optimizations and realized the optimization design of tractor frame structure.Through the contrast analysis on the calculation result before and after optimization,it is explained that the topological optimization technology based on variable density method could effectively carry through the optimization design on tractor frame,thus avoided blindness in structural design.The result of optimization provided reference for the structural design of products of the same kind. |
