Abstract
Dynamic deign is very important for avoiding an excessive vibration due to resonance in the case of wind turbines. In this study, the dynamic design of a small-size vertical axis wind turbine tower in operation has been modified to reduce the vibration level due to resonance and to enlarge the operational ranges. Also its dynamic characteristics including natural frequencies and excitation frequencies are evaluated before and after dynamic design modification. Acceleration responses were measured at 12 distributed locations for impact vibration tests, ambient vibration tests during non-operational and operational conditions, and braking tests during operational condition. The natural frequencies for the lowest 2 bending modes and the first torsional mode were estimated and it is verified that the dynamic modification is reasonably achieved.he vibration level due to resonance and to enlarge the operational ranges.
