【摘要】 在海波发电工程领域,波浪作用到海上浮体,使浮体产生摇摆运动从而吸收波浪的机械能。对海上浮体的摇摆运动进行准确建模,对于分析波浪发电装置的工作情况及评估波浪发电装置的能量转化效率具有重要意义。选取P-M波浪谱,根据实时海浪模型,采用线性叠加法仿真出长峰波随机海浪的波倾角,作为浮体横摇运动仿真的输入;建立浮体平台横摇运动模型并在长峰波随机海浪下对其横摇运动进行了仿真。仿真结果为海上波浪发电装置的后续分析研究提供了基础数据支持。更多还原

【Abstract】 In wave power generation area, sea wave acts on floating body and the floating body extracts the mechanical energy of sea wave due to its swinging. Modeling the swinging of the floating-body accurately is of great significance for analyzing the working condition of wave power device and evaluating its energy conversion efficiency. P-M wave-height energy spectrum was applied to simulate the wave slope angle of long-crested wave as the input of the rolling simulation of floating body using the linear superposition method according to real-time wave model. Then the floating body’s rolling motion was modeled and simulated under long-crested wave. The results provide basic supporting data for further study of wave power device.更多还原
