摘　　要：为了研究基于竖轴水轮机的漂浮式潮流能发电装置的水动力特性,设计试验模型和装置,进行静水拖航试验,测量系泊链拉力;控制水轮机转与不转,进行比较试验,测量水轮机转与不转时系泊链拉力和运动情况.试验表明:拖航速度为0.4m/s和0.5m/s时,水轮机不转,来流方向的1号和2号系泊链拉力相近;拖航速度为0.6m/s以上时,水轮机转动,1号系泊链拉力大于2号系泊链拉力,模型发生明显侧向位移;水轮机转动时1号系泊链的拉力为水轮机不转时的1.6～2.0倍;拖航速度增大,侧向位移变大,水轮机转动时的侧向位移量约为水轮机不转时的2.2倍;拖航过程中模型产生首倾和纵摇、横倾和横摇以及偏航,水轮机转动使模型的纵摇、横摇和偏航幅度增大.The test model and system were designed to study the hydrodynamic characteristics of the floating tidal power device with vertical-axis tidal turbine. The turbine was controlled to rotate or not during towing test in still water. In the two cases above, the tensile force on the mooring line and the movement of the model was compared. The test shows, when the towage speed is 0.4 m/s or 0.5 m/ s, the turbine will not rotate, and the tensile force on line 1 and 2 in flow direction are similar; when the towage speed is 0.6 m/s or more, the turbine will rotate, and the tensile force on line 1 is much greater than that on line 2, the model turns out an apparent lateral displacement; the tensile force on line 1 when the turbine is controlled to rotate is 1.6~2.0 times greater than that when the turbine is controlled not to rotate; the lateral displacement will increase when the towage speed increase, and the lateral displacement when the turbine is controlled to rotate is about 2.2 times greater than that when the turbine is controlled not to rotate; the trim by the bow, pitch, heel, roll, yaw will occur in towing test; the pitch, roll, yaw will increase when the turbine is rotating.
