| Abstract: | In order to reduce the mass of a gun effectively,optimization design for the structure of the upper carriage of a gun was studied.Combining the method of FEA with the structural topology optimization,an optimal mathematical model was set up according to the load features and design requirements of the upper carriage during firing.Computed the topological optimization of the upper carriage in OptiStruct,the mass of the upper carriage which is redesigned based on the optimal results decreased 12.17%,and the s... |
