摘　　要：可靠性分配是一种将可靠性指标合理分配到各子系统,确保机械系统稳定性的重要方法。为提高可靠性分配精度,提出一种基于综合因子模糊层次分析的机械系统可靠性分配方法。首先,建立系统层次结构,并采用层次分析法对不同影响因素进行权重分配。然后,运用综合因子模糊评价法对子系统进行模糊评价和不确定性信息处理,从而建立模糊关系矩阵确定因素组合权重,获得系统可靠性分配方案。最终,结合工业机器人系统进行分析,满足了工业机器人系统中降低减速器可靠性分配指标,提高机械臂和控制器可靠性分配指标的要求。Reliability allocation is an important method to reasonably allocate reliability indexes to each subsystem and ensure the stability of mechanical system.In order to improve the accuracy of reliability allocation,a reliability allocation method of mechanical system based on comprehensive factor fuzzy analytic hierarchy process is proposed in this paper.Firstly,the system hierarchy is established,and the analytic hierarchy process is used to distribute the weight of different influencing factors.Then,the comprehensive factor fuzzy evaluation method is used to conduct fuzzy evaluation and uncertainty information processing on the subsystem,so as to establish a fuzzy relationship matrix,determine the factor combination weight,and obtain the system reliability distribution scheme.Finally,combined with the analysis of industrial robot system,it meets te requirements of reducing the reliability allocation index of reducer and improving the reliability allocation index of robot arm and controller in industrial robot system.
