摘　　要：为了实现浅水域探测型无人水下航行器(Unmanned underwater vehicle,UUV)探测设备水下长时间工作,提出波浪能发电系统,可以将近水面的波浪能收集转化为电能。详细叙述永磁发电机的原理结构及设计参数;根据Lagrange方程建立系统的数学模型;采用Runge-Kutta方法求解简化的运动方程,研究不同海况条件下对发电性能的影响。研究结果表明提出的波浪能发电系统是合理可行的,在一般海况下,能够满足探测设备的能源需求。同时表明频率与幅度以及耦合横摇对发电性能影响比较大,而耦合垂荡对其影响基本可以忽略。研究结果将为后期波浪能发电系统的工程试验提供一定的理论依据。To achieve long operation time for the detection device on the detecting unmanned underwater vehicle （UUV） in shallow water, a wave energy conversion system is proposed. This can harvest wave energy and convert to electrical energy near water surface. The principle structure and the design parameters of the permanent generator are described in detail. The mathematical model of the system is established according to Lagrange Equation. The influence on the power performance is investigated over a range of sea state by solving the simplified equation of motion using the Runge-Kutta method. Research results show that the proposed wave energy conversion system is reasonable and feasible, which can satisfy the energy demand of the detection device under general sea state. And the results also show that the parameters of the amplitude, the period and the coupling motion of roll have a high impact, the impaction of coupling motion of heave can be negligible. The research results will provide a theoretical basis for the engineering test of the wave energy conversion system.
