摘要
为有效利用波浪能发电,对振荡浮子式双浮体波浪能装置进行分析。在对海洋结构物频域和时域的基本理论和计算方法进行分析的基础上,以双浮体波浪能装置为研究对象,提出一套基于势流理论的ANSYS-AQWA方法,对振荡浮子式双浮体波浪能装置的振荡运动进行模拟计算。利用Fortran对ANSYS-AQWA软件进行二次开发,在考虑线性脉冲串输出(Pluse Train Output,PTO)阻尼影响的条件下,将数值计算结果与NREL的试验结果相对比。针对特定的双浮体波浪能装置进行频域和时域的响应分析,为波浪能装置的进一步研究提供参考。
The principle and computing process of analyzing marine structures in frequency domain and time domain are introduced. A set of calculation method to simulate the oscillating motion of the double-floating-body wave energy device is developed based on AQWA software. The secondary development of ANSYS-AQWA taking the influence of linear PTO(Pluse Train Output) damping into account is conducted with Fortran language and the motion of the device is simulated with it. The simulation results are compared with the NREL test results. The response of the double-floating-body wave energy device is analyzed in frequency-domain and time-domain for illustration.
