在充分考虑海浪环境中各物理因素的基础上,对垂荡运动状态的波浪能发电装置的浮子和振子进行受力分析并构建二阶微分方程模型。使用四阶龙格-库塔方法进行微分方程组的数值求解,得到浮子和振子各时刻下的运动状态。并且利用功率关系式建立与阻尼系数相关的最大输出功率优化模型,使用遗传算法求解最优阻尼系数及最大输出功率。

Based on the comprehensive consideration of various physical influencing factors in the marine environment,the force analysis of the floater and oscillator of the wave energy power generation device in the heave motion state is carried out and a second-order differential equation model is constructed.Using the fourth order Runge-Kutta method,the differential equations are solved numerically and the time-related motion states of the floater and oscillator are gained.A maximum output power optimization model related to the damping coefficient is established according to the power relationship equation.The optimal damping coefficient and the maximum output power are solved by genetic algorithm.
