摘　　要：以解决小型海洋工作平台的能量供给问题为背景,提出一种基于横摇运动的波浪能装置,以箱式浮体结构为例,建立波浪能装置的运动模型和能量模型。采用数值分析的方法,对不同波浪环境、不同结构参数下装置的吸收功率密度、运动响应和能量输出模型的参数进行计算和分析。数值结果表明:基于横摇运动的波浪能装置更加适应在中、高频波浪环境下工作;通过合理设计浮体的稳定性以及对能量输出部分的优化,可实现对波浪能的最大吸收。In order to solve power supply of small-scale ocean platform, a wave energy converter based on roll motion was proposed, and a box-shaped buoy was selected as an example to research. The dynamic model and energy model of the converter were established, and the numerical simulation was applied to research the working conditions of the converter, such as the maximum absorption power density, optimum efficiency, corresponding roll amplitudes and optimum parameters of power-take-off （PTO） system. The results show that the converter is more adaptive to higher frequency waves; it can complete the optimum wave energy absorption by the well design of stability and the optimization of PTO.
