城市供水摘要：In this paper, a ball vibration absorber (BVA) is introduced for vibration control of offshore wind turbines. The dynamic respons of offshore wind turbines equipped with a BVA are prented. Both theoretical and experimental investigations are carried out. An analytical model for the wind turbine tower
广告媒介>黄小蕾system with installed BVA is developed bad on Lagrange''s equation. The BVA-structure integrated equations are derived and solved in both time domain and frequency domain. A ries of shaking table tests on a 1/13-scale wind turbine
model with and without a BVA were carried out to evaluate the effects of BVA on
the vibration mitigation of the wind turbine tower system under earthquakes and equivalent wind-wave loads. Numerical simulations of the system are performed
and compared with the experimental results. Good agreement 狐蝠
