摘要
在车身概念设计阶段引入拓扑优化设计方法,确定大客车车身的拓扑结构;对拓扑后的车身结构进行有限元分析,新车身具有质量轻、性能优良的特性,从而达到优化性能、降低质量的目的。
In order to obtain a reasonable body frame structure, topology optimization can be introuduced in the pe- riod of conceptual design of body structure. Then a finite element analysis is carried on the coach body in order to achieve the targets of less weight and better performance.
