摘要
为探究基于增材制造的拓扑优化设计方法在商用车轻量化领域的应用价值,将商用车后处理器支架作为试验对象,通过拓扑计算、几何重构、打印仿真分析等优化流程,提出了2种材料的优化方案设计,利用选区激光熔化(SLM)工艺完成实物增材制造.最终,2种方案均通过了8 000 km强化路台架试验验证,结果表明,基于增材制造的拓扑优化设计方法满足设计及性能要求.
Abstract
To explore the application value of topological optimization design method based on additive manufacturing in the field of commercial vehicle lightweighting,this paper proposes 2 types of optimization schemes through the optimization process of topological calculation,geometric reconstruction and print simulation analysis taking the commercial vehicle post processor bracket as the test object,and the Selective Laser Melting(SLM)process is utilized to complete the physical additive manufacturing.Finally,both schemes pass the verification of the 8 000 km enhanced road bench test,the results indicate that the topology optimization design method based on additive manufacturing fulfills the design and performance requirements.
