主　　题：coupling membership function fuzzy reliability 

摘      要：Field surveying shows that the failure of the steam turbine s coupling is due to fatigue that is caused by compound stress. Fuzzy mathematics was applied to get the membership function of the fatigue strength rule. A formula of fuzzy reliability of the coupling was derived and a theory of coupling s fuzzy reliability is set up. The calculating method of the fuzzy reliability is explained by an illustrative example.
