【摘要】 通常可以将模糊可靠性问题转化为常规可靠性问题来计算机械零件的模糊可靠性。由于模糊可靠性问题的复杂性 ,一般不会得到计算模糊可靠性的解析式 ,这时可以将其展开成级数的形式 ,得到模糊可靠性计算的级数表达式 ,或者得到转换的常规可靠性的级数表达式 ,然后再用仿真法估计机械零件的模糊可靠性。采取本文的方法 ,可以减少可靠性分析的计算量 ,在一些特殊的情况下 ,计算量会大大地减少。更多还原

【Abstract】 The fuzzy reliability of machine parts can be calculated by means of the transformation from the problem of fuzzy reliability into the problem of general reliability. Because of the complexity of the problem of fuzzy reliability, generally speaking, the analytical equation of calculating fuzzy reliability can not be obtained. In this case, if it can be expressed as a progression, then the progression of calculating fuzzy reliability may be obtained, or the progression of calculating general reliability may be obtained and the simulation method is used to estimate the fuzzy reliability of machine parts. By using the approach put forward in this paper, the calculation overhead for analyzing fuzzy reliability will decrease, sometimes decrease greatly.更多还原
