摘　　要：根据某型强击机液压系统故障统计资料,对该系统中使用的YB-20AH型液压泵运用最小二乘法做了可靠性分析,并计算了YB-20AH型液压泵寿命服从威布尔分布的参数m赞和t赞0,以及在不同可靠度下的可靠寿命,同时阐述了该液压泵严重内漏的故障原因,提出在现有使用与维护条件下延长液压泵寿命和预防内漏的措施。This paper analyzes the reliability of the YB-20H pump using the least square according the statistic data of fault in hydraulic system on a certain attacker, and calculates the Welbull distribution parameters and for YB-20H pump. The reliable life is also obtained under different reliability. The reason of interior leakage is given and the measures are put forward for preventing interior leakage to improve life of pump under the condition of existing maintenance.
