摘　　要：分析国内外竖轴潮流能水轮机实验台特点,设计了竖轴潮流能水轮机实验台,完成实验台调试、安装,并进行水轮机叶片预置攻角、尖速比、支撑臂等实验研究。所搭建的实验台可模拟8m/s以下潮流,测控系统额定功率5.5kW,水轮机最高转速150r/min;可实现不同尖速比、叶片预置攻角、叶片翼型、水轮机密实度、叶端盘和支撑臂等水动力性能实验和动力学特性实验研究;测控同时具备加载、发电、测量、耗能4个功能,克服了齿轮箱、电动机等部件自身功耗对水轮机性能测试结果的影响,大大拓展了实验台的功能和应用空间。实验结果表明,所设计的水轮机最大能量捕获效率为35%,支撑臂对水轮机能量捕获效率的影响随尖速比提高而增大。研究结果为潮流能综合开发利用提供了具有借鉴意义的实验台设计方案和实验数据。Characteristics of domestic and international test rig for vertical axis marine current turbine were analyzed, vertical axis marine current turbine best rig was designed, assembled and commissioned, and blade preset attack angle, ti Pspeed ratio and blade arm experiments were carried out. The test rig can achieve the functionality as： maximum flow rate 8m/s, measurement and control system power 5.5kW, turbine maximum rotating speed 150r/min; also hydrodynamic test of tip speed ratio, airfoil, turbine compaction, suspension disc, and dynamics test are supported in the designed rig. In the meantime, monitoring and control system which has four main functions at loaded, power generation, measurement, energy dissipation at the same time, overcomes turbines measurement errors lead by power consumption of gearbox and motor, greatly expanding the functionality and applications of this test rig. The test results shown that maximum energy capture efficiency of the designed turbine is 35%, influence of blade arm on turbine efficiency increases with increasing the tip speed ratio. The research work is a good reference for current turbine design and the research data are the supply for the comprehensive development and utilization of the tidal current energy.
