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.

在涉及旋转机械的各种行业中，可靠的健康监测和生命预后（PHM）系统的发展一直是各种事业的重点，以防止机器加速性能降解，意外故障或灾难性失败。大多数机器故障与涉及轴承的机械传输系统有关。例如，风力涡轮机中超过75％的变速箱故障归因于磨损或损坏的轴承。轴承通常在可变且有时出乎意料的负载下在恶劣的环境中运行，从而导致其在不同的故障模式下降解。这些断层不仅可能导致系统性能恶化，而且可能导致设备损坏的系统故障，从而导致巨大的经济损失。通过与位于渥太华的公司Gastops Ltd.的合作，拟议的研究的目的是开发一种新型的轴承PHM系统，以可靠地估算使用多源数据对工业环境中轴承的当前和未来健康状况的可靠估算。拟议的轴承PHM系统将提供预先警告故障，启用预测性维护并提高系统可靠性。目的是帮助加拿大制造业，航空航天和能源部门改善资产利用，并在全球市场中保持竞争力。
