STRESS AND MODEL ANALYSIS OF THE BLADE OF A ROTATING WIND TURBINE UNDER THE CONDITION OF ICING

Abstract

Abstract: Taking rotor blades of rotating ice as the research object, the artificial icing test of blades is carried out. According to the experimental results, a finite element model of wind turbine blades is established, and the stress and modal analysis of blades with different icing thickness are carried out. The analysis results show that the amount of ice change is positively correlated with the stress magnitude of the blades. The different natural frequencies of the blades will be significantly changed by the amount of ice, causing the fatigue damage and deformation of the wind turbine blades, which verifies the results of artificial experiments.

Key words: rotating wind turbine blade, modal analysis, ice cover, ANSYS simulation, natural frequency
