Thermal-structural Coupling Analysis of Spindle-bearing System of Grinding Wheel of Surface Grinder

  • 摘要: 以某型数控卧轴矩台平面磨床为研究对象,对其砂轮主轴-轴承系统进行了温度分布与热变形的有限元仿真。基于滚动轴承热态特性理论与传热学理论,利用ANSYS Workbench软件对主轴-轴承系统进行稳态和瞬态的温度场仿真,得到了轴承滚子与内外圈滚道温度随时间的变化规律;根据热-结构耦合分析理论和温度场仿真结果,对主轴-轴承系统进行了热-结构耦合分析,得到了主轴在径向、切向与轴向3个方向的热位移与热应力的变化规律,从而揭示了由轴承摩擦产生的热效应造成的温度升高与主轴产生热变形及热位移之间的关系。
