对某型直升机滑动舱门锁闭系统报警故障进行分析,得出锁闭机构微动开关安装结构不合理以及频繁的冲击载荷是故障的主要原因,对锁闭机构的结构进行了优化设计并进行了验证,验证结果表明改进后的锁闭机构满足滑动舱门锁闭要求。
Based on the analysis of the alarm failure of the sliding door lock system of a helicopter, the conclusion is drawn that the structure of the micro switch of the lock mechanism is unreasonable and the frequent impact load is the main reason for the failure. The structure of the lock mechanism is optimized and carried out After verification, the verification results show that the improved locking mechanism can meet the requirements of sliding door locking.
