利用水动力计算软件AQWA对双浮体式振荡浮子波浪能发电装置主浮体进行仿真分析,对不同尺寸垂荡板的主浮体进行建模仿真,并就各自RAOs、激振力、附加阻尼和附加质量进行频域分析。结果表明,在波浪频率低于0.3 Hz时,垂荡板尺寸对其影响尤为明显;当波浪频率分别大于0.2 Hz、0.36 Hz和0.35 Hz时,垂荡板尺寸分别对RAOs、激振力和附加阻尼失去影响;对于同一吃水线、不同垂荡板尺寸的主浮体,波浪频率对其附加质量有较大影响,且垂荡板尺寸越大影响越严重。
The main floating body of double floating body oscillating buoy wave power plant was simulated and analyzed by using AQWA software. The main buoy of different size heave plate was modeled and simulated. In addition, the main buoyancy of RAFO, exciting force, additional damping and additional mass Perform frequency domain analysis. The results show that when the wave frequency is lower than 0.3 Hz, the heave plate size has a significant impact on it. When the wave frequency is more than 0.2 Hz, 0.36 Hz and 0.35 Hz, respectively, the heave plate dimensions affect RAOs, excitation force and additional For the main buoy with different heave plate sizes, the wave frequency has a greater influence on the additional mass of the same buoy, and the larger the heave plate size, the more serious the influence will be.
