چکیده انگلیسی
Structural health monitoring (SHM) is essential for ensuring the structural safety performance during the service life. The process is of paramount importance in the case of the floating wind turbine (FWT) due to the structural parts, subjected to the marine environmental risky conditions. In this paper a fuzzy-based damage detection method, using dynamic response of the FWT structure, is proposed. In the first step, the nonlinear motion equations of the FWT system are derived using the theorem of angular momentum and Newton's second law. Then the variation values of the mean amplitude of dynamic response and frequency characteristics of the structure due to stiffness changes of mooring lines (simulated damage) are considered as input features to the fuzzy system. Also the fuzzy system is trained based on calibrating of the membership functions by defining the damage classes properly. The proposed method is applied on two types of the FWT, Tension Leg Platform (TLP) and Spar. The simulation results show that the proposed method is able to identify the damage classes with acceptable success rate (SR).
