摘　　要：论文以浮子式波浪能发电装置的最大输出功率为目标函数,通过对装置及其工作过程进行物理抽象和数学建模,该研究得到了波浪能装置的基本力学模型;通过牛顿力学建立微分方程组并求解,得到了系统的具体运动参数;使用多种智能算法计算得到了使波浪能装置发电效率最高的直线阻尼器和旋转阻尼器的阻尼系数。在基础模型中,通过不同的智能算法:全局搜索、粒子群优化算法、模拟退火优化算法,得到了功率的最大值,并比较了三种算法的运行时间和迭代次数。考虑到浮子在海水中除垂荡运动外还作摇荡运动,改进模型中加入绕转轴的力学分析得到浮子、振子的动力学方程,并通过前述的智能算法求解最优阻尼系数。ion and mathematical modeling of the device and its working process,the basic mechanical model of the wave energy device is obtained.The damping coefficients of the linear damper and the rotating damper which make the power generation efficiency the highest are calculated by using a variety of intelligent algorithms.In the basic model,the maximum power is obtained by global search,particle swarm optimization algorithm and simulated annealing optimization algorithm,and the running time and iteration times of the three algorithms are compared.Considering the swaying motion of the buoy in addition to the heaving motion in the seawater,the mechanical analysis of the rotating shaft is added to the improved model to obtain the dynamic equations of the buoy and the vibrator.
