摘　　要：针对灯船遭遇风浪时会发生剧烈的横摇运动使得船体蕴含着丰富的机械能,提出一种安装在灯船舱室内的发电装置,该装置通过捕获船体机械能从而实现对波浪能的间接回收利用。设计装置的基本结构并阐明其工作原理,以MATLAB软件作为仿真计算平台,根据船舶横摇运动和装置中滑块的运动规律建立二者耦合的质量-阻尼-弹簧模型,并利用Newmark-β方法进行求解。计算得到装置功率、滑块重力侧分力和滑块角位移等数据,并探究不同弹簧刚度K和系统阻尼系数C组合对装置能量捕获效果的影响,结果显示当K=300 N/m和C=30 N/(m/s)时装置平均功率最大为169 W。Aiming at the fact that the lightship will have violent rolling motion when encountering wind and waves, which makes the ship contain rich mechanical energy, a power generation device installed in the lightship cabin is proposed, which can realize the indirect recovery and utilization of wave energy by capturing the mechanical energy of the ship hull. The basic structure of the device is designed and its working principle is introduced. Using MATLAB software as the simulation platform, a coupled model is established based on rolling motion of the ship and the motion of the slider in the device, and the mass-damping-spring model of the slider motion is solved using the Newmark-Beta method. The power of the device, the gravity side force of the slider and the angular displacement of the slider are calculated. The effect of different combinations of spring stiffness K and system damping coefficient C on the energy capture of the device was calculated. The results show that the maximum average power of the device is 169 W when K=300 N/m and C=30 N/(m/s).
