摘　　要：机构的参数与失效判据中往往存在模糊变量与随机变量相互混合的情况,并具有性能伴随时间退化等故障。针对这一现象,完成了包含模糊、随机参数的机构时变可靠性模型建模与计算。In the parameters and failure criteria of the mechanism,fuzzy variables and random variables were often mixed with each other,and there were failures such as performance degradation with time.Aiming at this phenomenon,this paper completes the modeling of the mechanism's time-varying reliability model including fuzzy and random parameters,and calculate.
