摘　　要：根据外场数据对某机前起落架的随动系统作了可靠性分析，找出了设计中的薄弱环节。通过对更改后的随动系统的磨损量的估算，评估了该系统的可靠性寿命，其首翻期增长一倍。Based on the sport data on the fault information gathered from operating maintenance field, a reliability analysis of the follower system of the front landing gear of a certain aircraft is made and its weak parts in design are found. The reliability life of a modfication of the system is assessed by its wear capacity, which leads to its first maintenance time to be doubled and all maintenance times to be decreased by five.
