摘　　要：三自由度机械手系统在工业上有着广泛的应用,其能否有效的运行取决于可靠性分析,论文通过对FMEA和FTA的总结和对比提出了综合分析的步骤和流程,并用该方法对某三自由度机械手系统进行了可靠性分析,建立了故障树(FTA)和故障模式影响及危害性分析表(FMEA),最后找到了系统薄弱环节并对各个薄弱环节进行评估。The 3-DOF manipulator is widely used in Industry and its ability to operate effectively directly depends on reliability analysis. The step and procedure of integrated analyzing and evaluating method is summarized by contrast FMEA and FTA firstly, then the reliability of 3- DOF manipulator is analyzed and evaluated using this method and establishes the FTA and FMEA. At last finding out the weaknesses of the system and evaluating each weaknesses.
