Abstract With the increasing popularity of wind energy, offshore wind turbines (OWTs) are currently experiencing rapid development. The tower is one of the most significant components of the OWT. However, the tower will not only stand its own weight and weight of the top structure, but also be surrounded by harsh wave and wind loading conditions. Therefore, it is necessary to apply a structural health monitoring (SHM) system to monitor the health condition of the OWT towers in real-time. In this study, inverse Finite Element Method (iFEM) is applied to monitor the tower of an OWT under both static and dynamic loading conditions. The total displacements and von Mises stresses obtained from iFEM analysis are compared against reference results and optimum sensor locations are determined.

使用 iFEM 方法对海上风力涡轮机塔架进行结构健康监测

摘要 随着风能的日益普及，海上风力涡轮机（OWT）目前正在经历快速发展。该塔是 OWT 最重要的组成部分之一。然而，塔不仅要承受自身重量和顶部结构的重量，还要承受恶劣的波浪和风荷载条件。因此，有必要应用结构健康监测（SHM）系统来实时监测 OWT 塔的健康状况。在这项研究中，逆有限元方法 (iFEM) 被应用于在静态和动态载荷条件下监测 OWT 的塔。将从 iFEM 分析获得的总位移和 von Mises 应力与参考结果进行比较，并确定最佳传感器位置。
