海上漂浮式风力发电机按旋转轴的方位分为漂浮式水平轴风力发电机和漂浮式垂直轴风力发电机。与传统的浮动式风力发电机相比，浮动式风力发电机的主要优点是不受风向影响，发电系统的位置较低，降低了安装和维护成本。在以往的研究中，将风力涡轮机视为刚体，对漂浮式垂直轴风力发电机的动力学特性进行了广泛的研究。而风力涡轮机尺寸的增大有利于实现更高的性价比。在研究漂浮式风力涡轮机的动力特性时，需要考虑叶片和塔架等细长结构的弹性变形。基于多体动力学和运动学理论，建立了H型浮式垂直轴风力机的刚柔耦合动力学方程。介绍了涡轮机结构的固有运动特性，分析了“动力刚化”现象。计算了在复杂环境载荷作用下浮体的运动以及塔架和叶片的振动。分别对浮体、塔架和叶片进行了时域和频域仿真。此外，还研究了气动载荷和波浪载荷对浮式垂直轴风力机的影响。研究了刚性和柔性结构的传力性能。
Offshore floating wind turbines are classified into floating horizontal axis wind turbines (HAWTs) and floating vertical axis wind turbines (VAWTs) according to the orientation of rotating shaft. Compared with the traditional floating HAWTs, main advantages of floating VAWTs are the independence of wind direction and the lower position of power generating system, which reduce the installation and maintenance costs. Dynamical characteristics of floating VAWTs were widely studied in the preceding researches by tackling the wind turbine as a rigid body. However, the increasing size of wind turbine is beneficial to achieve higher cost performance. The elastic deformations of slender structures including blades and tower should be considered when the dynamical characteristics of the floating wind turbine are studied. In this paper, rigid-flexible coupling equations were established to investigate the dynamic behavior of H-type floating VAWT based on multi-body kinematics and dynamics. Natural motion performances of the wind turbine structures were presented and the phenomenon of “dynamic stiffening” was analyzed. Motions of the floater and vibrations of the tower and blades were computed under complex environmental loads. Time domain and frequency domain simulations were carried out to study the dynamic response of floater, tower and blades, respectively. Besides, the effect of aerodynamic loads and wave loads on the floating VAWT was researched. Load transfer performance through rigid and flexible structures was investigated.
