燃料电池客车骨架结构的有限元分析与优化设计

Finite Element Analysis and Optimal Design on a Fuel Cell Bus Frame

建立燃料电池客车骨架的有限元模型,计算弯曲、一轮悬空等典型工况下的静态强度、刚度及振动模态,对骨架结构进行优化设计,保证骨架结构的安全性及可靠性。

The authors build a finite element model of a fuel cell bus frame and analyze the static strength and stiffness under the typical conditions,such as bending condition,one wheel hanging condition. And the natural mode is also analyzed. The analysis results give some suggestions on the frame structure optimization design so as to keep the safety and the reliability of the fuel cell bus frame.
