| Summary: | Mechanical model of a MW wind turbine tower was established and the fundamental frequency of bending vibration and torsional vibration was obtained by Rayleigh method in this paper. The influence of the diameter, thickness, taper angle, up structure mass, offset of mass on the fundamental frequency of tower was studied. The influence of dimension and position of door frame on the fundamental frequency was studied by Finite Element Method. The results of Finite Element Method show good consistency with that of Rayleigh method by-comparison. |
