摘要
轴承故障工况动力学建模是研究轴承因故障所产生的振动响应与故障形式内在联系的理论基础。在综合考虑时变接触刚度、滚珠是否位于负载区、接触形态、润滑油膜等一系列动力学干涉因素的基础上,分析了不同故障形式下轴承的动力学响应,揭示了不同故障下的轴承振动机理,为基于振动信号实现滚动轴承故障形式判断提供理论支撑。
The dynamic modeling of bearing fault condition is the theoretical basis to study the internal relation between bearing vibration response caused by fault and fault form.Based on comprehensive consideration of a series of dynamic interference factors such as time-varying contact stiffness,whether the ball is located in the load zone,contact shape and lubricating oil film,etc.,the dynamic response of bearings under different fault forms was analyzed,which reveals the mechanism of bearing vibration under different faults and provides theoretical support for realizing fault form judgment of rolling bearing based on vibration signal.
