摘　　要：作动器是飞机飞行控制系统的关键部件,试验是验证作动器是否满足设计要求的可靠手段。从某作动器试验故障入手,对作动器的设计、制造、试验环节进行了全流程分析,定位了故障原因,并研究故障机制,提出了改进措施。为类似产品的故障分析提供了一套可借鉴的方法,所采用的强度分析方法为类似产品的设计、验证提供了参考。Testing is effective validation means for actuator, which is the critical component of aircraft flight control system. Based on the experiment fault of actuator, the design manufacturing and experiment process of the actuator were analyzed. The true rea- son was confirmed and improved measures were proposed. The analysis methods of fault, strength and fatigue can be future reference for other actuator.
