摘要： 为了验证某新能源轻客电池包支架的强度性能，首先建立电池包支架有限元模型，然后根据不同工况的受力状态，加载不同方向的重力场，以此对其进行静态强度分析，分析结果表明其最大应力值均小于极限值，均符合设计要求。最后基于集成平台对电池包支架的厚度值进行优化设计，优化之后得到其最优值，优化之后的强度性能仍然能够满足使用要求，并且其重量减轻了 7.7%，达到了轻量化的效果。

Abstract: Aiming at verifing the strength performance of a new energy light commercial bus battery pack bracket. Firstly,the finite element model of the battery pack bracket was established. it was strength analyzed by loading gravity field in different directions based on stress state of different working conditions, the analysised result showed that its stress was less than the yield strength of the material, so it could meet design requirements. Lastly, the thickness of battery pack bracket was optimization design based on integration platform, the battery pack bracket optimal thickness were obtained, its strength performance could meet the requirements after optimization, and its weight was reduced by7.7%, the effect of light weight was reached.
