摘　　要：为实现某品牌汽车电池箱体轻量化设计,避免电池箱体在机械冲击和碰撞环境下发生安全事故,以电池箱体在机械冲击和碰撞环境下的位移、应力和应变为评价指标,采用Ansys Workbench软件对原设计模型进行分析,根据分析结果对底面和侧面进行优化,优化后电池箱体在机械冲击和碰撞环境下的位移、应力和应变均符合设计要求,优化后电池箱体的重量由原来的110.56 kg下降至59.11 kg,轻量化率为46.54%,最大位移碰撞时间由60 ms延长至80 ms,有效提升了电池箱体的安全性能。In order to lighten the weight of a certain brand of car battery box and avoid safety accidents in mechanical impact and collision environments,the displacement,stress,and strain of the battery box under mechanical impact and collision environments were used as evaluation indicators.Ansys Workbench software was used to analyze the original design model.Based on the analysis results,the bottom and side surfaces were optimized,and the displacement,stress and strain of the optimized battery box under mechanical impact and collision environments met the design requirements.After optimization,the weight of the battery box decreased from 110.56 kg to 59.11 kg,with a lightweight rate of 46.54%.The maximum displacement collision time was extended from 60 ms to 80 ms,effectively improving the safety performance of the battery box.
