摘　　要：将整个汽车门锁看成是由多个构件组成的运动链系统,画出其工作示意图,介绍了汽车门锁的整体结构、组成部分及其工作原理;应用Pro/E软件,对汽车门锁系统进行了3D建模和装配;运用系统分析方法之一的失效模式及影响分析法,从可靠性角度对汽车门锁系统进行分析,建立了汽车门锁系统的失效树,并确定其重要元件及主要失效形式。The whole automobile door lock is considered as a kinematic link system which is made of many components. Its working schematic diagram is drawed up, the whole stnacture ; components of an automobile door lock and its working principle are introduced. Software Pro/Engineer has been applied for 3D modeling and assembling. By applying the fault pattern and in- fluence analysis method, which is one of the system analysis methods, from the standpoint of reliability, the mobile door lock system has been studied. A fault tree of the system is built up, and significant parts and main fault patterns are determined.
