摘要


本文在前人所建立的模型基础上,引入了滚动体的随机滑动和周期性变化的振动传递函数,并综合考虑了静态载荷分布和故障点的位置,建立了滚动轴承局部故障的随机振动数学模型。模型使用MATLAB语言编程实现,并通过给其混入噪声进行故障诊断试验,验证了该模型在轴承故障机理分析和故障诊断方面的实效性。

Abstract

The stochastic mathematical models of the vibration signals produced by localized faults in rolling element bearings are established in this paper. Comparing with the models set up by the former researches, the models are improved by introducing the random slip of rolling elements and the periodically varying transfer function of vibration, and taking into account the static load distribution and the positions of the faults. The models are performed by MATLAB. The noise is added in and the fault diagnostic test is carried out. The result validates that the models had practical value on the mechanism analysis of bearing faults and the fault diagnosis
