摘要
目的分析高速响应电磁阀常见故障模式，评估其工作寿命．方法采用寿命试验，故障模式、影响及危害度分析（ＦＭＥＣＡ）和生存分析法．结果电磁阀失效模式主要有液压密封失效、电磁线圈短或断路、弹簧疲劳失效、连接支架松动等．工作寿命为３０×１０５次．结论为了提高电磁阀性能指标，在材料选用、加工精度和装配工艺等方面需进一步改进，工作寿命有待于提高．
Aim To analyze the common failure mode of the HSV and estimate its working life Methods Life experiment, FMECA, and the existence analysis were used Results The failure modes of the HSV include the failure of the hydraulic sealing, the short or broken circuit of the electromagnetic coil, the weary failure of the spring, and the loose of the support, etc The working life is 3×105 times Conclusion In order to improve the performance of the HSV, there are further works in the selection of material, the accuracy of manufacture, and the assembly technology The working life also needs improving
