| Abstract: | A single-rotor system dynamic model as well as its dynamic response, together with the interference model of exciting-natural frequency was studied. From the randomness of influencing factors on both exciting frequency and natural frequency, and the fuzziness of resonance vibration failure in the single-rotor system, the corresponding membership function is deduced by analyzing the relationship between the distributing characteristics of the membership function and the system running state. The formulas employed to calculate fuzzy dynamic reliability of the system are also given. The applied validity of fuzzy reliability in this system is validated by a numerical example. |
