【Abstract】 n this paper.a method for calculating the natural frequency and eigenmode of power turbine’s tower.the wind effect and displacement response of the tower along wind direction. and the wind effect and displacement response produced by the tail vortex across wind direction is introduced. The response caused by wind turbine’s rotation is discussed. Using this method some calculation examples are given. It is a convenient way to design wind turbine’s tower.更多还原
