摘要：针对从燃料电池轿车副车架质量冗余问题，从轻量化研究入手，使用计算机辅助设计软件进行了结构分析，采用铝合金材料，对某燃料电池汽车副车架进行了结构优化，并对新设计的副车架进行了校核。分析结果表明，新副车架在轻量化的同时，各项性能都较原件有很大的改善，该方案为燃料电池汽车轻量化的进一步发展提出了建议。

Abstract: Aiming at the problem of viceframes quality redundancy and from the start with lightweight study of fuelcell car, using optimization software with computeraided, a former viceframes structure of fuelcell vehicle was redesigned. By aluminum alloy materials, the structural optimization of the electric cars frame was done, the checking and analyzing of the new frame were processed. The results of analysis show that the lightweight performance of the frames new deputy are much better than the originals at the same time, the suggestions of the fuel cell vehicless lightweight are further put forward.
Key words: lightweight; structural optimization; aluminum alloy; viceframe
