摘要
为有效地模拟三维波浪,从已有的统计观测结果出发,应用P-M谱和SWOP方向函数的基础上,建立了风浪的三维随机波面数学模型,该模型采用多个随机余弦波叠加来模拟随机波浪曲面。最后利用Matlab实现了该算法,结果表明这种方法能有效地模拟三维随机海浪。
To simulate 3D wave effectively,from the viewpoint of statistics and observation results from oceanography,a mathematic model of 3D wind-driven random wave surface was built up based on Pierson-Moscowitz random wave height energy spectrum and direction function suggested by Stereo Wave Observation Project（SWOP）.The model makes use of several consine waves superposingto simulate random wave surface.Finally,the simulation and display of 3D random wave were realized by means of Matlab.The simulated maximal wave height was compared with the standard wave height of different level waves.The simulation results indicated that this method is an effective approach to simulate 3D random wave.
