摘要
利用时间序列中的自回归模型(AR模型),基于数值分析软件MATLAB,编制了模拟脉动风速时程的程序,最后得出薄壁高墩竖向10个节点的脉动风速时程,对模拟谱与目标谱进行了比较得出低阶的AR模型能够很好的模拟脉动风速时程的结论。
Using AR model in series,on the base of MATLAB,it made a programme of time of simulated pulsation wind speed.At last it worked out the time value of wind speed of thin-walled high pier in ten different nodes.Through comparing simulation specturm and target spectrum,it made a conclusion that low-level AR model could simulate pulsation wind time very well.
