摘 要: 本文介绍了一种通过检测波浪的垂方、北向和西向位移,对位移数据和波浪进行统计分析,进行傅立叶变换研究其功率谱密度和方向频率分布的方法,并对之进行了试验研究.该研究对船舶耐波性的研究、海洋工程的规划设计和海洋气侯预报具有重要意义. This paper introduces a method for measuring and analyzing sea waves; carries out a statistical analysis on the heave,north and west displacement of the wave; and applies Fourier transform to gain the power spectral density and direction spread,which are testified through experiment.The research is of great significance to the study of ship's seaworthness,ocean engineering design of and marine weather forecast.
