摘　　要：建立了锂离子电池组的三维力学模型,对电池组进行了耐大量级力学条件仿真和实验测试。结果表明,两者应力应变变化趋势基本一致,反映了所建模型和施加边界条件的合理性。在此基础上,提出了电池组力学结构的优化方案并进行了仿真分析,优化后电池组应力场分布更加合理。A three-dimension mechanical model was built for the lithium-ion battery pack. Both simulation and experimental test of lithium-ion battery pack enduring high-level mechanical condition were conducted. The results show their consistency in stress and strain variation trend, meaning the rationality of the built model and the given boundary condition. On this basis, an optimization scheme for the mechanical structure of lithium-ion battery pack was proposed and simulated. The results indicate that stress field distribution of lithium-ion battery pack is more rational after optimization.
