通过使用振动分析来监测滚动轴承的状态是检测部件退化早期阶段的一项成熟技术。然而，当转速低于16r/min时，这种成功并不能反映出来。在这样的速度下，轴承缺陷产生的能量可能不会显示出明显的特征变化，因此使用传统的振动测量设备无法检测到。本文研究了应力波分析在1.12r/min(0.0187赫兹)转速下检测轴承早期损伤的适用性。此外，它还审查了在监测转速低于16r/min的轴承方面所做的工作。
Condition monitoring of rolling element bearings through the use of vibration analysis is an established technique for detecting early stages of component degradation. However, this success is not mirrored at rotational speeds below 16r/min. At such speeds the energy generated from bearing defects might not show as an obvious change in signature and thus becomes undetectable using conventional vibration measuring equipment. This paper presents an investigation into the applicability of stress wave analysis for detecting early stages of bearing damage at a rotational speed of 1.12 r/min (0.0187 Hz). Furthermore, it reviews work undertaken in monitoring bearings rotating at speeds below 16 r/min.
