Rolling-element bearings are a key component in rotating machinery¹ such as turbomachinery, electric motors, machine tools and gearboxes. In recent years, the use of such bearings has increased dramatically, yet bearing failure has impacted negatively the maintenance of machinery and has increased downtime costs.^1–3 Unsurprisingly, there is considerable interest in developing more effective techniques to monitor bearing conditions that can help to identify the likely occurrence of faults.

诊断装有减振器的转子系统的滚动轴承故障

滚动轴承是旋转机械^1（例如涡轮机械，电动机，机床和变速箱）中的关键组件。近年来，此类轴承的使用已急剧增加，但是轴承故障对机械的维护产生了负面影响，并增加了停机成本。^1-3毫不奇怪，人们对开发更有效的技术来监控轴承状况感兴趣，这有助于确定可能的故障发生。
