WIND POWER GENERATOR

摘要

PURPOSE: A wind power generator is provided to include a vibration absorber which corresponds to the excitation frequency and the vibration response of the tower by controlling the length in a length direction of the height direction of a tower, thereby selectively controlling the vibration absorbing frequency. CONSTITUTION: A wind power generator includes a tower (10) and a vibration absorber (20). The vibration absorber is provided in the tower to absorb the vibration transferred to the tower and control the length in a length direction of the height direction of a tower, thereby controlling the vibration absorbing frequency. The vibration absorber includes a linear guide (21), a vibration absorbing member (22), and a weight body (23). The vibration absorbing member is supported to the linear guide, and thus absorbs the vibration transferred to the tower and moves in the length direction. The weight body is provided at the end portion of the vibration absorbing member.
