The development of reliable health monitoring and life prognostics (PHM) systems has been the focus of various undertakings, in a wide array of industries involving rotary machinery, to prevent machine accelerated performance degradation, unexpected malfunction, or catastrophic failures. Most machine failures are related to mechanical transmission systems involving bearings. For instance, over 75% of gearbox failures in wind turbines have been attributed to worn or damaged bearings. Bearings often operate in harsh environments under variable and sometimes unexpected loads, leading to their degradation under different fault modes. These faults may not only deteriorate the system performance but may also lead to system failures with equipment damage, resulting in significant economic losses. Through collaboration with Gastops Ltd., an Ottawa-based company, the objective of the proposed research is to develop a novel bearing PHM system for reliable estimation of current and future health conditions of bearings in industrial environment using multi-source data. The proposed bearing PHM system will provide advance warning of failure, enable predictive maintenance, and improve system reliability. The goal is to help the Canadian manufacturing, aerospace, and energy sectors improve asset utilization and remain competitive in the global market.

在涉及旋转机械的广泛行业中，开发可靠的健康监测和寿命预测(PHM)系统一直是各种事业的重点，以防止机器加速性能退化、意外故障或灾难性故障。大多数机器故障都与涉及轴承的机械传动系统有关。例如，超过75%的风力涡轮机变速箱故障都是由于轴承磨损或损坏造成的。轴承经常在恶劣的环境中工作，承受可变的、有时是意想不到的载荷，导致它们在不同的故障模式下退化。这些故障不仅会恶化系统的性能，还可能导致系统故障和设备损坏，造成重大的经济损失。通过与总部位于渥太华的Gastops有限公司合作，拟议研究的目标是开发一种新型的轴承PHM系统，以便使用多源数据可靠地估计工业环境中轴承的当前和未来健康状况。建议的轴承PHM系统将提供故障预警，实现预见性维护，并提高系统可靠性。目标是帮助加拿大制造业、航空航天和能源行业提高资产利用率，并在全球市场上保持竞争力。
