基于 ABAQUS 的角接触球轴承动力学仿真分析

为研究角接触球轴承在不同转速下温度及位移变化,基于 Palmgren 摩擦生热理论,综合考虑轴向载荷、切向摩擦和法向摩擦等边界条件,在 ABAQUS 软件中建立了轴承完全热力耦合模型。对轴承外圈施加固定的轴向载荷,并对内圈加载不同的转速,使用显示求解器求解轴承在不同转速下各部件温度和轴承内圈位移变化。仿真分析表明,该模型能够准确地反映轴承的温升以及轴承内圈位移情况,为轴承选取合适工作转速区间提供理论支撑。

Dynamic Simulation Analysis of Angular Contact Ball Bearing Based on ABAQUS

In order to clarify the temperature and displacement changes of angular contact ball bearings at different rotational speeds , based on the Palmgren friction heat generation theory , a fully thermal mechanical finite element model which has considered boundary conditions such as axial load , tangential friction and normal friction was established in ABAQUS software.The bearing outer ring is applied to a fixed axial load , and the inner ring is loaded with different speeds.The temperature of each component of the bearing and displacement of the inner ring will be carried out by using the Explicit solver.The simulation analysis shows that the model can accurately reflect the temperature rise of the bearing and the displacement of the bearing inner ring.This conclusion provides theoretical support for selecting the appropriate working speed range of the bearing.
