Study on the Gyroscope Effect of Floating Offshore Wind Turbine Based on Modal Analysis

Abstract

In order to study the influence of gyroscope effect on floating fan, the DTU 10 MW fan is chosen as the research object, the floating platform is ITI energy barge platform, and the equivalent model is established by ANSYS finite element software. The state of floating fan at sea is simulated and modal analysis is carried out to determine the natural frequency and mode shape, so as to effectively avoid the occurrence of resonance, and to compare the working state with the non-working state. The influence of gyroscope effect on the natural frequency and vibration mode of fan is determined. By drawing Campbell diagram to determine the critical speed of the wind turbine, the rationality of the actual working speed of the wind turbine is confirmed.
