针对海上风机受风荷载和地震作用时塔筒顶部会产生较大振动的问题，通过有限元软件ABAQUS对导管架海上风机进行建模，并提出双向调谐质量阻尼器(Bidirectional Tuned Mass Damper,双向TMD)减振方案，研究双向TMD在风荷载、地震作用及风-地震联合作用下对海上风机的减振效果。结果表明，双向TMD减振装置对导管架海上风机在风荷载、地震作用及风-地震联合作用下塔筒顶部位移的减振效果为36.95%～47.64%;在风荷载作用下塔筒顶部加速度的减振效果为49.70%～61.78%,在地震作用下和风-地震联合作用下塔筒顶部加速度的减振效果为6.22%～25.63%。

Aiming at the large vibration problem at the top of the tower when the offshore wind turbine is subjected to wind load and earthquake action, the jacket offshore wind turbine was modeled by the finite element software ABAQUS, and a bidirectional bidirectional tuned mass damper(TMD) vibration reduction scheme was proposed to study the vibration reduction of offshore wind turbine based on bidirectional TMD under wind load, earthquake action and wind-earthquake combined action. The results showed that the vibration reduction effect of the bidirectional TMD vibration reduction device on the top displacement of the jacket offshore wind turbine under wind load, earthquake action and wind-earthquake combined action was 36.95%-47.64%. Under the action of wind load, the vibration reduction effect of the acceleration at the top of the tower was 49.70%-61.78%. Under the action of earthquake and wind-earthquake combined, the vibration reduction effect of tower top acceleration was 6.22%-25.63%.
