该文基于线性波理论,从载体在波浪中的运动方程出发,以两种不同的优化角度推导了波能装置输出能量最大时的表现形式,最后以圆柱体作为波浪能转换的载体分析了两者方法的差异。数值计算表明在同一水深下,波能装置浮体的水线面决定了波能装置最优转换效率的趋势,而吃水深度决定了波能装置可达到的最大转换效率;对波能装置参数优化后运动在共振点的波能装置其转换效率并不是最大,而优化后的最大转换效率并不发生在共振点上。
Based on the theory of linear wave and the equation of motion of the carrier in the wave, this paper derives the expression of the wave energy device with the maximum output energy from two different optimization angles. Finally, using the cylinder as the carrier of wave energy conversion, The difference in method. The numerical calculation shows that the water surface of the wave energy device floating body determines the optimal conversion efficiency of the wave energy device under the same water depth, and the draft depth determines the maximum conversion efficiency achievable by the wave energy device. After optimization of the wave energy device parameters The conversion efficiency of the wave energy device at the resonance point is not the maximum, and the optimized maximum conversion efficiency does not occur at the resonance point.
