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
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英汉互译词典
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
soil
and compared with the experimental results. Good agreement
