摘要: 该文建立考虑桩-土耦合作用的单桩式海上风力机整机多体动力学模型,结合水动力和空气动力,借助Matlab/Simulink搭建风力机的联合仿真模型。对安装于机舱内的单调谐质量阻尼器(STMD)和多重调谐质量阻尼器(MTMD)系统进行设计,并在运行工况和泊机工况下进行仿真分析。研究表明,相比于正常运行工况,泊机工况下的调谐质量阻尼器(TMD)振动抑制性能更优,对塔基前后弯矩标准偏差有着最优的控制效果,且MTMD系统中TMD的数量与系统振动抑制性能存在非线性关系。

Abstract: This paper establishes a multi-body dynamics model of a complete monopile offshore wind turbine considering the pile-soil interaction effect. A co-simulation model is then built. Finally, a single-TMD (STMD) system and a multiple-TMD (MTMD) system installed in the nacelle are designed and evaluated under the normal operation and the parked cases. The results show that the TMD systems exhibit better performance under the parked case than under the normal operation case. The standard deviations of the tower-base bending moments are suppressed more significantly than other evaluation indices. Furthermore, it is found that there is nonlinear relationship between the TMD number and the performance of MTMD.

Key words: offshore wind power, vibration control, wind turbines, structural dynamics, wind-wave excitation
