摘要
为了处理考虑多层影响因素下的复杂机械系统可靠性分配问题,分析了传统的综合因子可靠性分配方法,提出了一种考虑二层因素影响的综合因子可靠性分配法,即对传统的可靠性影响因素进行层次划分,建立考虑二层因素影响的全局指标数学模型,进而确定各子系统的全局指标权重,分配得到各子系统的可靠度。通过一个工程案例说明了该方法的具体应用并证明了其简单有效性。
In order to deal with the reliability allocation problem considering multi-layer factors of complex mechanical systems,the traditional integrated factor reliability allocation method was analyzed,an integrated factor reliability allocation method was proposed considering the influences of two-layer factors.In this method,the levels of traditional reliability influencing factors were divided,a global index mathematical model was established considering the influences of two-layer factors,and then the global index weights of each subsystem were determined,the reliability of each subsystem was allocated.Finally,an engineering case was given to illustrate specific applications of the method and the simplicity and effectiveness.
