摘　　要：为解决海洋仪器的长期能源供应问题,基于永磁材料的电磁特性,结合易于起振的摆式俘能机制,提出了一种与小体积球形浮标相结合的永磁式波浪能发电装置。详细论述了装置的发电原理和设计方案,推导了装置在波浪激励下的运动模型。依靠AQWA与Maxwell软件进行了联合仿真并对装置进行了参数优化,最终仿真结果表明:在波浪入射角度β=0°,波浪周期T=3.5s,波浪高度H=0.6m的波况下摆锤做周期T_(p)=2s,幅值A_(p)=15°的往复振荡运动,单相绕组产生的感应电动势最大可达27.7V,最佳输出功率为2.07W,可有效满足海洋仪器的供电要求。In order to solve the problem of long-term energy supply for marine instruments,based on the electromagnetic proper-ties of permanent magnet materials,combined with a pendulum energy capture mechanism that is easy to vibrate,a permanent magnet wave energy power generation device combined with a small-volume spherical buoy is proposed.The power generation principle and design scheme of the device are discussed in detail,and the motion model of the device under wave excitation is de-duced.Relying on AQWA and Maxwell to carry out joint simulation and optimize the parameters of the device.The final simula-tion results show that the pendulum performs a reciprocating motion with a period of T_(p)=2s and an amplitude of A_(p)=15°under the wave condition where the wave incidence angleβ=0°,the wave period T=3.5s,and the wave height H=0.6m.The maximum in-duced electromotive force generated by the single-phase winding can reach 27.7V,and the best output power is 2.07W,which can effectively meet the power supply requirements of marine instruments.
