【摘要】 波浪能是海洋中重要的可再生清洁能源，提高波浪能装置的能量转换效率是波浪能利用的关键问题。对浮子、振子、中轴以及能量输出系统构成的波浪能转换装置进行数学建模，并建立了双自由度的浮子、振子垂荡和纵摇运动方程。当直线阻尼系数为常数时，基于微分方程理论，得到浮子、振子垂荡运动位移解析表达式，以及浮子、振子在指定时刻的位移和速度。基于MATLAB编程，利用龙格-库塔法和穷举法求解了该模型。更多还原

【Abstract】 Wave energy is an important renewable and clean energy source in the ocean,and improving the energy conversion efficiency of wave energy devices is a key issue in the utilization of wave energy. We mathematically models a wave energy conversion device which is composed of a float, oscillator, central axis, and energy output system, and establish a two-degree freedom equation for the heave and pitch motion of the float and the oscillator. When the linear damping coefficient is constant,based on differential equation theory,analytical expressions for the heave motion displacement of the float and the oscillator,as well as the displacement and velocity of the float and the oscillator at a specified time, are obtained. The runge kutta method and exhaustive method were used to solve the model through MATLAB programming.更多还原
