| Abstract: | By adopting the variable density method, the topoiogical optimization model that took the total flexibility of structure as the objective function and the volume of structure as the constraint was established. Utilizing the topological optimization tool in the finite element software hyperworks the weight reduction design has been carried out on the initial designing scheme of the tumbler structure of train bogie axle box. The result showed that the topology based optimization technology could obtain both economic and safety structural scheme. |
