客车骨架局部结构的多工况拓扑优化设计

Topology Optimization Design of Bus Local Framework Structure Under Multiple Conditions

以某12 m全承载式混合动力城市客车为研究对象,提出一种多工况拓扑优化的结构设计方法,对客车乘客站立区的底架结构进行改进,并进行刚度、强度对比。结果表明,改进后的骨架的力学性能有所改善。

The paper takes a 12 m monocoque hybrid bus as the research object,puts forward a structure de-sign method of topology optimization under multiple conditions to improve the framework structure of passen-gers standing areas,and compares the stiffness and strength. The results show that the mechanical proper-ties of the improved framework are improved.
