摘　　要：基于叶素动量理论和伯努利原理建立桨叶动力学模型,从能量捕获效率最大化原则出发,采用非线性优化方法求解得到桨叶外形参数,并制作出桨叶进行实验测试。结果表明,优化后的桨叶在设计流速附近运行时能获得更大的功率,并更接近理论预测值,可验证该动力学模型的正确性和有效性。The hydrodynamic model of the blade was proposed based on the theory of blade element momentum and Bernoulli principle, the blade shape parameters were optimized for the purpose of maximum power capturing efficiency by using a nonlinear optimization procedure, and the optimized blade was manufactured and tested as well. Test results showed that the power captured by the optimized blade is in good accordance with the theoretical calculation value and reached the maximum when the blade is forced to run by the current at the design velocity, which proves the accuracy and validity of the proposed hydrodynamic model.
