【摘要】 现场调查表明，汽轮机转子的损坏是由于转子与联轴器的联接部位在复合应力作用下的疲劳破坏所引起的，这里应用模糊数学原理推出了疲劳极限的隶属函数，根据模糊可靠性理论推导出了转子抗疲劳的模糊可靠度计算公式，建立了转子的模糊可靠性分析理论，并结合实例说明了转子模糊可靠度的计算方法。　　　睡舞更多还原

【Abstract】 Field surveying shows that the rotor’s failure of the steam turbine is because of the rotor’ S fatigue failure which is caused by the combined stress. Apply the fuzzy mathematics to get the membership function of the endurance limit. Calculating formula of the rotor’ s fuzzy reliability was deduced out by using the theory of the fuzzy reliability. Theory of rotor’s fuzzy reliability is set up. The calculating method of fuzzy reli- ability is explained by an illustrative example.更多还原
