摘　　要：为探究轴承故障对轴承振动的影响,以实验室机组的调心轴承为对象,利用ABAQUS软件建立轴承常见的内外圈故障的有限元模型以及简化的轴承座模型,以验证在轴承座表面布置传感器的合理性。以ABAQUS-explicit显式算法进行动力学特性分析,并且通过正常轴承与故障轴承的动力学特性对比,将从轴承座表面提取的正常轴承和故障轴承的仿真信号进行了时域和频域对比。模拟实际将振动传感器安装在轴承座上提取振动数据,为开发轴承的在线检测系统提供一定基础。To explore the influence of the bearing fault of bearing vibration, with aligning ball bearing of lab unit as object,using the software of ABAQUS finite element models of common inside and outside the circle of bearing fault and simplified model of bearing seat, to verify the rationality of the arrangement of sensors in the bearing-sur- face. With ABAQUS-explicit analyses dynamic explicit algorithm, and through the normal bearing compared with the dynamic characteristics of bearing fault, normal bearing will be extracted from the surface of the bearing seat and fault of bearing simulation signal in time domain and frequency domain comparison. Simulate the actual vibration sensor in- stalled on the bearing seat to extract data, for the development of bearing on-line detection system to provide certain basis.
