摘要为研究变载工况下滚动轴承内部接触特性，在考虑轴承运动部件动态效应的基础上，采用非线性弹簧模拟滚子与保持架的相互作用，建立了圆柱滚子轴承动力学模型。运用四阶定步长Runge-Kutta算法对运动微分方程组进行求解，获得了变幅值、变频率下内圈与滚子接触特性及其影响规律以及不同形式周期波动载荷作用下保持架动态接触特性。研究结果表明：滚子与保持架前端碰撞主要发生在承载区，后端碰撞主要发生在非承载区；随波动幅值的增加，承载区中间区域滚子与内圈接触力增大而进出承载区时影响较小；低频载荷作用下内圈质心轨迹较为集中，随波动频率的增加，内圈载荷呈现缓慢增大的趋势同时内圈存在下移趋势，高频载荷作用下内圈质心轨迹紊乱分散，内圈与滚子接触不稳定，内圈质心在竖直方向呈现震荡趋势。载荷波动时滚子与保持架前端碰撞程度加剧，周期性波动载荷作用下承载区保持架碰撞力峰值从大到小依次是方波、正弦波、三角波、稳定工况。

Abstract：On the basis of considering the dynamic effect of bearing moving parts,the interaction between roller and cage was simulated by nonlinear spring,a dynamic analysis model of cylindrical roller bearing was established to research the internal contact characteristics of rolling bearing under variable load. The Runge-Kutta algorithm with fourth-order fixed step was used to solve the differential equations of motion. The contact characteristics between inner ring and roller and its influence law under variable amplitude and frequency, as well as the dynamic contact characteristics of cage under different forms of periodic fluctuating load were obtained.The results show that the collision between the roller and the front of cage occurred in load zone, reversely, the collision between the roller and the rear of cage occurred in non-load zone.With the increase of fluctuation amplitude, the contact force between roller and inner ring increases in load zone, but the influence is small when entering and leaving the load zone.Under the action of low-frequency load, the trajectory of inner ring centroid is relatively concentrated,with the increase of fluctuation frequency, the load of inner ring increases slowly,simultaneously,the inner ring tends to move upward.Under high frequency load the centroid trajectory of inner ring is disordered and dispersed and the contact between inner ring and roller is unstable,the inner ring vibrates in the vertical direction.When load fluctuates, the degree of collision between the roller and the front of cage intensifies. The peak value of cage collision force from large to small is square wave, sine wave, triangular wave and stable working condition.

Key words： rolling bearing load fluctuation cage dynamic contact dynamics
