Abstract Aiming at the problem of ice-induced frequency lock-in (FLI) vibration of offshore wind turbine (OWT) in ice area, the ice-induced vibration response analysis was performed, and the wind turbine vibration control method in ice area was proposed based on 3-D pendulum tuned mass damper (3D-PTMD).Based on the self-excited vibration theory of Mttnen-Blenkarn, ANSYS parametric design language (APDL) was used to develop the wind turbine self-excited vibration analysis program in ice area.Based on the blade element momentum theory, considering Prandtl blade-tip loss correction and Grauert correction, the aerodynamic load of wind turbine blade was calculated by using the program developed with MATLAB.The national renewable energy laboratory (NREL) 5 MW offshore monopile wind turbine was taken as an example.Considering the once-in-a-year ice situation in Bohai Sea of our country, the vibration response analyses of the wind turbine structure under different directions of ice-wind combination conditions were performed.The ice speed range for FLI event happening was deduced, and vibration responses of the wind turbine tower with and without 3D-PTMD were compared.The results showed that the ice speed corresponding to FLI happening of the monopile OWT is within the range of 0.01 m/s-0.06 m/s; when ice and wind acting on the turbine structure in the same direction, the ice speed range corresponding to FLI happening of the monopile OWT is the maximum and the vibration response of the tower structure is the maximum; 3D-PTMD can significantly suppress in-plane and out-plane vibration responses of the tower under combined action of ice-wind loads to greatly improve its service safety; the study results can provide a technical support for safe operation of OWTs serving in ice area.
