Wind turbines are designed to operate according to an estimated profile of the environmental conditions of a given site. The IEC 64100-1 standard defines wind turbine classes according to these conditions. During the design, the manufacturers make the dimensioning of this equipment according to each class. The expected life of the wind turbines when they are designed is nominally 20 years. Today, the average age of wind turbines in Quebec is about 10 years. The high costs of acquisition, installation and unavailability drive wind farm operators to question the optimal maintenance policy to adopt. As a result, the development of decision support tools to establish an economically justified choice (e.g., repair or replacement) while minimizing the risk associated with operating such equipment. Thus, the precise estimate of the residual reliability of this type of equipment becomes a strategic issue for the fleet operators.This project implements multi-disciplinary work encompassing various areas such as fracture mechanics, reliability, prognosis and learning. In addition to operational data already available, we plan to instrument three wind turbines. With the usual sensors (e.g. vibration, temperature ...) and the installation of strain gauges at the connection between the blades and the hub (maximum stress point), it's expected to capture the actual profile of the mechanical stress induced by the wind. . This captured profile will be extrapolated to simulate a plausible life profile for a given site. Knowledge of the terrain topography will extrapolate the profile to similar sites. Fatigue will be studied primarily as the main mode of failure. The projected works will contribute to better knowing the nature and the amplitudes of the mechanical stresses on the structure, which will allow a more precise computation of the residual lifespan, and to establish precise predictions.

风力涡轮机被设计成根据给定地点的环境条件的估计轮廓来操作。IEC 64100-1标准根据这些条件定义风力涡轮机等级。在设计过程中，制造商根据每个级别对该设备进行了尺寸标注。风力涡轮机在设计时的预期寿命通常为20年。今天，魁北克风力涡轮机的平均年龄约为10年。购置、安装和不可用的高成本促使风电场运营商质疑应采用的最佳维护策略。因此，决策支持工具的开发，以建立一个经济合理的选择（例如，修理或更换），同时使与操作这种设备相关的风险最小化。因此，对此类设备的剩余可靠性进行精确估算成为船队运营商的战略问题。该项目实施了包括断裂力学、可靠性、预测和学习等各个领域的多学科工作。除了已有的运行数据外，我们还计划对三台风力涡轮机进行检测。使用常见的传感器（例如振动、温度.）以及在叶片和轮毂之间的连接处（最大应力点）安装应变片，预计可以捕获由风引起的机械应力的实际轮廓。.将对捕获的曲线进行外推，以模拟给定部位的合理寿命曲线。了解地形地貌后，可将剖面外推至类似地点。疲劳将主要作为主要失效模式进行研究。预计的工作将有助于更好地了解结构上机械应力的性质和幅度，这将有助于更精确地计算剩余寿命，并建立精确的预测。
