摘要
应用一系列力学关系,给出了深海沉浮式养殖网箱的运动方程组,在网箱下潜深度的研究中采用绕射理论和Morison方程进行了波浪力分析,讨论了网箱的下潜深度随波浪的波高、波长及周期的变化情况,得出下潜水深比较小时深海网箱的波力变化快,当达到某一个下潜深度以后,波力的变化趋于平缓,从而为深海网箱选用最佳工况提供了一种参考方法。
Submersible depth of a columniform- lift offshore cage was analyzed hy a series of equations in mechanics, including diffraction theory and Morison equation, and the dynamic equations for the column lift offshore cage were presented. The submersible depth of the cage varied with the variation of wave - length, wave - height and wave - period regularly. The wave forces varied rapidly in shallow sinkage and vary slowly in deep - seated submersible depth .
