摘要

基于波浪能清洁无污染、分布广等优点,首先,从分析波浪能发电装置在海水中垂荡和纵摇运动的角度出发,分别对浮子和振子进行受力分析,依据动静法建立了动力学方程,并确定了波浪能装置纵摇运动转轴位置,得到了浮子和振子的转动惯量函数.随后,运用变步长四阶五级Runge-Kutta-Felhberg算法进行求解,获得了浮子和振子从静止到进行垂荡和纵摇运动各时刻的运动状态.最后,以平均输出功率为目标函数,运动微分方程和阻尼系数是否恒定为约束条件,建立了波浪能输出功率的最优化模型,使用变步长搜索法和多起点全局搜索算法,求解了最大平均输出功率及相应参数.

Abstract

Based on the advantages of wave energy,such as clean,pollution-free and widest distribution,this paper analyzes the force on the float and vibrator respectively from the perspective of analyzing the heave and pitch motion of the wave energy generating device in seawater.After establishing the dynamic equation based on the dynamic and static method,the position of the rotation axis of the wave energy device's pitch motion is determined,and the moment of inertia function of the float and vibrator is obtained.Then the variable step size four-order and five-order Runge-Kutta-Felhberg algorithm is used to solve the problem,and the motion state of the float and vibrator is obtained at every moment from rest to sag and pitch motion.Finally,with the average output power as the objective function and the constant motion differential equation and damping coefficient as the constraint conditions,the optimization model of wave energy output power is established.The maximum average output power and the corresponding parameters are solved by using variable step size search method and multi-starting global search algorithm.
