摘　　要：为减轻质量,空间用锂离子蓄电池壳体设计为Φ50的圆柱体,壳体材料采用铝合金,壳体各部分之间通过电子束焊连接。分析计算和强度试验结果表明,该种壳体工作时的承压安全系数不小于3.0,耐压力疲劳次数超过60 000次,新设计圆柱形锂离子蓄电池壳体力学性能可以满足空间长寿命应用的要求。In order to ease weight,the shell of Φ50 lithium-ion cell used in space has been designed as cylinder form,which material adopted aluminum metal alloy,and each part of the body combined by electron beam welding.Conclusions of analysis show that,when the shell on work,the coefficient of press safety will be no smaller than 3.0,and the number of bear to press tired over 60 000 times.This shell designed as cylinder form for Φ50 lithium-ion cell can satisfy the request of longevity life worked in space.
