本文研究了浮动式垂直风力机（VAWT）的空气动力学和运动性能，其中风力机为h型，浮动基础为桁架梁式。基于双多流管理论，推导了考虑浮式基础运动的风力机气动载荷计算公式。建立了h型浮式VAWT的浪-沉-纵非线性耦合方程。对5mw h型浮式VAWT的空气动力学和运动性能进行了研究，分析了浮式基础运动对气动载荷的影响。结果表明，浮式基础的运动对空气动力学的影响是不可忽视的。将h型浮式VAWT的运动与Φ-type浮式VAWT进行了比较：两者具有相同的浮式基础、额定输出功率、系泊系统和总排水量。结果表明，h型浮式VAWT具有更好的运动性能，其喘振、升沉和纵摇的平均值均比Φ-type浮式VAWT小得多。
Aerodynamics and motion performance of the floating vertical wind turbine (VAWT) were studied in this paper, where the wind turbine was H-type and the floating foundation was truss spar type. Based on the double-multiple-stream-tube theory, the formulae were deduced to calculate the aerodynamic loads acting on the wind turbine considering the motions of the floating foundation. The surge-heave-pitch nonlinear coupling equations of the H-type floating VAWT were established. Aerodynamics and motion performance of a 5 MW H-type floating VAWT was studied, and the effect of the floating foundation motions on the aerodynamic loads was analyzed. It is shown that the motions of the floating foundation on the aerodynamics cannot be ignored. The motion of the H-type floating VAWT was also compared with that of the Φ-type floating VAWT: they have the same floating foundation, rated output power, mooring system and total displacement. The results show that the H-type floating VAWT has better motion performance, and the mean values of surge, heave and pitch of the H-type floating VAWT are much smaller comparing with the Φ-type floating VAWT.
