Bearings are the most common elements in any rotary machines that compromise their structural integrity. Failure of any single bearing can be disastrous and can lead to break or seizure of other machines elements and in some circumstances it can even cause severe workplace injuries. Condition monitoring of bearing elements has received considerable amount of attention in the past few decades. However, prediction of the Remaining Useful Life (RUL) of bearing elements within reasonable accuracy is still a challenging task. At Ontario Power Generation (OPG) assessment of the life expectancy of bearing elements once a defect is identified by conventional vibration measurements is extremely important and it has been a continuous challenge. It is crucial to reliably ensure that nuclear equipment where a faulty bearing is identified can last until their next scheduled outage to avoid loss and of production and revenue. The main objective of this project is to provide a methodology for determining the Remaining Useful Life (RUL) of the rolling element bearings when the early sign of failure is detected.

轴承是任何旋转机器中最常见的元件，会损害其结构完整性。任何单个轴承的故障都可能是灾难性的，并可能导致其他机器元件的损坏或卡住，在某些情况下甚至可能导致严重的工作场所伤害。在过去的几十年里，轴承元件的状态监测受到了广泛的关注。然而，在合理的精度内预测轴承元件的剩余使用寿命（RUL）仍然是一项具有挑战性的任务。在安大略发电公司 (OPG)，一旦通过传统振动测量发现缺陷，就对轴承元件的预期寿命进行评估极其重要，并且一直是一项持续的挑战。可靠地确保发现故障轴承的核设备能够持续到下次计划停运，以避免损失以及生产和收入至关重要。该项目的主要目标是提供一种方法，用于在检测到早期故障迹象时确定滚动轴承的剩余使用寿命 (RUL)。
