摘要

针对角接触球轴承动态刚度和阻尼特性分析的问题，本文建立了考虑基础响应的单自由度动态参数测试力学模型；搭建了轴承动态参数识别试验装置，测试及分析了不同的载荷条件对轴承径向和轴向动态刚度及阻尼的影响。试验结果表明：随着轴向载荷增大，轴向刚度、径向刚度逐渐增大，轴向阻尼、径向阻尼先减小后增大；随着径向载荷增大，轴向刚度、径向刚度逐渐增大，轴向阻尼、径向阻尼先增大后减小再增大。

Abstract

Considered dynamic stiffness and damping characteristics of angular contact ball bearing, a single DOF dynamic model of bearing which considered foundation responses was proposed to identify dynamic parameters in this paper; an experimental device for identifying dynamic parameters was developed to test and analyze the effects of radial and axial dynamic stiffness and damping under different load cases. Experimental results showed that with the axial load increased, the axial stiffness and the radial stiffness increased, the axial damping and the radial damping decreased and then increased; with the radial load increased, the axial stiffness and the radial stiffness increased, the axial damping and the radial damping increased and then decreased and then increased.
