项目摘要

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.

可靠的健康监测和寿命预测 (PHM) 系统的开发一直是涉及旋转机械的众多行业中各种事业的重点，以防止机器加速性能下降、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。轴承通常在恶劣的环境下运行，承受变化的负载，有时甚至是意外的负载，导致轴承在不同的故障模式下发生性能退化。这些故障不仅会降低系统性能，还可能导致系统故障并导致设备损坏，造成重大经济损失。通过与位于渥太华的 Gastops Ltd. 合作，拟议研究的目标是开发一种新型轴承 PHM 系统，利用多源数据可靠地估计工业环境中轴承当前和未来的健康状况。拟议的轴承 PHM 系统将提供故障预警、实现预测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保持在全球市场的竞争力。
