Abstract: In order to suppress the lateral vibration of anisotropic rotor systems, a grounded nonlinear energy sink(GNES)and a linear dynamic vibration absorber(LDVA)were designed. Firstly, the structure, working principles and some inherent characteristics of GNES were introduced. Then, the dynamic models and equations of the coupled systems composed of GNES, LDVA and rotor systems were established respectively. Finally, the vibration suppression effects of two kinds of vibration absorption devices were analyzed by the numerical method. The results showed that the vibration suppression performance of GNES is better than that of LDVA under the given parameters.

Key words: anisotropic rotor system, GNES, LDVA, vibration suppression, performance comparison
