摘要
研究了随机波浪载荷作用下海洋平台的TMD振动控制,建立了TMD—海洋平台振动模型,从TMD能量分析的角度对TMD参数进行了优化设计;同时将状态反馈引入系统,依据结构响应的反馈信息确定控制力,运用极点配置法,选取适当的反馈增益K,从而进一步达到控制结构振动的目的。
The structural vibration control of offshore platform under random wave loading by using Tuned Mass Damper （TMD） is investigated. The model of offshore platform- TMD is established. Tuned Mass Damper （TMD） is installed on the offshore platform for sharing the energy of main structure, so that vibration of the main structure can be controlled. Optimal TMD parameters can be determined by analyzing the energy dissipation and transmission of the structure-TMD. Meanwhile, states feedback is introduced in the structure -TMD. Optimal controlling force is determined based on feedback from structural responses. By use of pole assignment method, feedback gain is selected suitably. The vibration could be reduced further.
