摘要：

In order to solve the problem associated with four-span eight-bearing rotors (2N) and four-span five-bearing rotors (N+1) with too large vibrations around the critical speed, a kind of magneto-rheological damper based on fuzzy proportion integral differentiation (PID) control was designed. The 2N and N+1 supported four-span rotors benches were established to simulate the starting process and the vibration characteristics of 2N and N+1 supported rotor systems were studied. One magneto-rheological damper was installed at each shaft and the effect of magneto-rheological dampers on rotor systems was investigated. The results show that the coupling of each shaft of N+1 supported shafting is stronger and the vibration of adjoining shaft can be excited easily. The fuzzy PID controller can output appropriate control current for dampers according to the amplitude of rotors. The dampers can effectively suppress the vibrations of 2N and N+1 supported four-span shafting and the amplitudes of rotors are controlled within the target range. © 2016, Editorial Board of Journal of Huazhong University of Science and Technology.
