摘要: 时域分析法是对结构进行风致振动分析的主要方法之一,而采用该法的前提是要有一系列的风速(或风压)时程样本.详细介绍了风速时程AR模拟方法及AIC准则,并对此技术进行了编程实现.所模拟的结果表明:AR模型可有效地模拟具有空间时间相关性的节点脉动风速时程.

关键词: AR模型;AIC准则;空问相关性;MATLAB

Abstract: Time-domain analysis method is one of the major methods of analyzing wind-induced structure vibration,but the method needs a series of samples of wind speed or wind pressure time-series.The simulation of time-series of wind speed using AR model and AIC rule was introduced and analyzed in detail.The method was implemented,andan example was given to verify it.The results show that the AR model is effective in simulating wind speed time-seties with time and space correlativity.

Key words: AR model;AIC rule;space correlativity;MATLAB
