基于数字积分法的模糊可靠性计算模型

在研究系统的模糊可靠性问题时，对模糊可靠度的计算是一个十分困难的问题。为了解决此问题，提出一种基于数字积分法的模糊可靠性计算模型，它重点解决工程实际中的随机应力0模糊强度模型问题。在此基础上提出一种模糊可靠性的数学运算法则，它可以用来计算机械部件、传感器、电子单元等的模糊可靠性。基于这种计算模型，提出一种计算鱼雷圆柱形壳体模糊可靠性的方法，它为鱼雷可靠性分析建立了一种系统组成单元模糊可靠性的基础。最后通过实例进行了计算分析，计算结果证明这种方法与工程实际是一致的。

In engineering experience it is difficult to compute fuzzy reliability of torpedo system, To resolve above problem, a computational model of fuzzy reliability based on numerical integral algorithm is presented. The mathematical basis of this computational model is that the fuzzy probability can be computed with the computational method of conventional probability by use of the numerical integral algorithm Based on this computational model, a numerical algorithm is given which can be applied to compute the fuzzy reliability of cylindrical shell, This establishes a basis for the reliability analysis of systems consisting of components with fuzzy reliability. In the end the computation results fits the engineering experience.
