Research on connection structure of aluminumbody bus using multi-objective topology optimization

摘要：

　　For connecting Aluminum Alloy bus body aluminum components often occur the problem of failure,a new aluminum alloy connection structure is designed based on multiobjective topology optimization method.Determining the shape of the outer contour of the connection structure with topography optimization,establishing a topology optimization model of connections based on SIMP density interpolation method,going on multi-objective topology optimization,and improving the design of the connecting piece according to the optimization results.The results show that the quality of the aluminum alloy connector after topology optimization is reduced by 18%,and the first six natural frequencies are improved and the strength performance and stiffness performance are obviously improved.
