摘要:
在基于弹性力学的正常滚动轴承二自由度动力学模型的基础上,考虑外圈局部点蚀缺陷宽度以及深度对接触变形的影响,引入滚动体通过缺陷时接触变形量的变化,建立了外圈产生单一局部故障的滚动轴承的动力学模型.通过仿真,证实了当外圈产生单一局部缺陷时,滚动轴承振动信号的低频成分为滚动体通过外圈的频率及其倍频这一在滚动轴承故障诊断中常用的结论,并合理解释了倍频产生的原因;最后通过实验进一步证实了所建立模型和仿真结果的有效性
Abstract:
On basis of the two degrees of freedom vibration model of the normal rolling elements bearing established by using the elastic mechanics and consideration of the influence of the width and depth of the local defect, the vibration model of rolling elements bearings with an outer race defect was constructed through adding the change of the contact deflection between the rolling element and races which took place when the rolling element passed the defect. Through the numerical simulation, it was verified that the frequency components of the vibration signal of the of rolling elements bearings with an outer race defect in low frequency region were the frequency of the rolling element passing the defect and its multiple frequencies, which often was used in faults diagnosis of the rolling element bearing. The reason of occurrence of the multiple frequencies was explained reasonably. The experiment further testified the validity of the model and the simulated results
