摘要
滚动轴承作为旋转机械的关键部件,局部存在缺陷将严重影响旋转机械的性能。针对外圈局部存在缺陷将产生冲击的问题,基于显示动力学有限元法,应用LS^DYNA软件,对滚动轴承外圈存在局部缺陷的情况进行了动力学仿真,获得了外圈局部缺陷产生的冲击形式。仿真结果为滚动轴承局部缺陷模型的建立提供一定的理论依据。
As a key component of rotating machine, the local defects of rolling bearing can seriously undermine the performance of the rotating machinery. Based on the explicit dynamic finite element method, using the software LS- DYNA the dynamic simulation of local defects of rolling bearing outer ring is imitated and acquire the impact form caused by the local defects of rolling bearing outer ring is aequired. The simulation results will provide some theoretical basis for establishing the of local defect model of rolling bearing.
