摘要/Abstract

摘要： 为了抑制各向异性转子系统的横向振动，设计了一种接地式非线性能量阱(grounded nonlinear energy sink， GNES)和一种线性吸振器(linear dynamic vibration absorber， LDVA).首先介绍了GNES的结构、工作原理及一些固有特性;然后分别建立GNES和LDVA与转子系统组成的耦合系统的动力学模型;最后，采用数值法分析了两种吸振装置的抑振效果.结果表明，在给定参数下，GNES的抑振性能优于LDVA.

关键词: 各向异性转子系统, GNES, LDVA, 振动抑制, 性能比较

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
