| 摘 要： | 基于AR模型的基本原理和算法,利用MATLAB软件编写随机海浪的模拟程序,模拟出以P-M单参数谱及其方向谱为靶谱的随机海浪波高时程样本。计算出前若干阶AR模型的精度和计算时间,比较得出一个精度合理、效率较高的自回归阶数。通过与目标相关函数和功率谱密度的对比,说明用AR模型进行随机海浪的模拟是可靠的。

| Abstract: | Based on AR model, the program for random wave simulation is given used the Maflab. According to the target spectrum of P-M spectrum and its direction spectrum, the sample of random wave height time history is simulated. A high efficiency order of AR model is obtained by comparison the accuracy of former few-order AR model. Compared the auto-correlation and power spectrum density function of simulation sample with the objective auto-correlation and power spectrum density function respectively, it indicates that the AR model for simulation of random wave is reliable. |
