Topology Optimization in Lightweight Design of Frame

WANG Yuan-shao,WANG Li-juan,CHEN Zong-yu,WU Xiang-qing(School of Mechatronics Engineering,Nanchang University,Nanchang 330031,China)  
The frame was used as object in this research.The topology optimization was performed by Opti struct with density method,through the changes of the biggest stiffness problem into the minimum flexibility.The density contour was used as the idea for distribution of the lightweight design material,and the model was rebuilt.At last,the feasibility of the method was verified and the mass decreased of 3.11% under the conditions of all kind of basic performance.The results provided reference for the further application of topology optimization in vehicles and parts.
