摘　　要：对车架的拓扑优化设计做了研究,在原有重型载货汽车车架模型的基础上,设定拓扑优化区域和优化参数,通过变密度法将连续体离散成[0,1]分布的模型,对于密度较小的区域采取去除材料的办法形成空洞,留下来的材料为横梁的分布位置,为后续的车架设计提供一个思路。The paper researches on the topological optimization design of frame,Established the topology optimization region and the optimized parameter in the original heavy-duty truck frame model＇s foundation,the model was separated to 0-1 distribution model based on variable density method,the small density region area was abandoned and formed the holes,the remained material is the location of crossbeam.This is a new method for vehicle frame design.
