| 摘 要： | 以某氢燃料电池运输车车架为研究对象,对现有底盘燃料罐的布置方式进行优化,提出了将原来在车架上方的燃料罐布置到车架两侧的方案,采用有限元建立原车架模型和优化后车架模型,对两种车架的典型工况进行有限元分析。结果表明,优化后车架强度既满足设计要求,也不会产生共振,符合该运输车设计要求。这种车架的布置方法不仅可以规避原方案中燃料罐占据较大空间的弊病,还可以扩大载货使用空间。

| Abstract: | This paper takes the frame of a hydrogen fuel cell transport vehicle as the research object.The layout of the existing chassis fuel tank is optimized,and a plan to place the fuel tank on either side of the frame is proposed which was originally on top of the frame.The original frame model and the optimized frame model were established by finite element method,and the finite element analysis was carried out for two typical working conditions of the frame.The results show that the optimized frame strength meets the design requirements,and does not produce resonance,conforms to the design request.This arrangement can not only avoid the disadvantage that the fuel tank occupies large space in the original plan,but also expand the space for carrying cargo. |
