摘　　要：研究了航天J18DMA系列失效的压接电缆的失效模式,以GJB5020—2001标准为指导,通过实验对失效电缆的电阻和抗拉力数据进行了统计和分析。对异常的失效情况,采用金相分析方法分析了失效机理,最后对解决方案进行了探讨。The failure modes of aerospace J18DMA series crimping cable were studied. Guiding by the GJB5020-2001 standards, the resistance and tensile strength of the failed cable were statistically investigated. For some abnormal failure, the failure mechanism of the crimping cable was studied by using metallographic analysis. Finally, the results and the solutions were discussed.
