摘要

高速滚动轴承的负荷分布特性对转子系统的动态特性有着非常重要的影响,为尽可能得到真实的轴承载荷分布情况,采用拟动力学分析方法,并通过考虑轴向负荷、径向负荷、离心力以及陀螺力矩对其的影响,建立了滚动轴承的动力学分析模型。采用Matlab编程求解非线性方程组,研究了不同径向负荷、轴向负荷及转速条件下滚动轴承的负荷分布特性,得到了滚动轴承接触角和变形的变化规律。

Abstract

Load distribution characteristics of rolling bearing at high speed have important effects on the rotor system’s dynamic characteristics. In order to simulate the actual load distribution,the dynamic analysis model of rolling bearing is established by quasi-dynamic,simultaneously considering radial load,axial load,centrifugal force and gyroscopic moment acted on the rolling bearing,and study the rolling bearing load distribution under different radial load,axial load and speed conditions by MATLAB programming for solving nonlinear equations,the effect rules of contact angle and deformation are analyzed by program.
