摘要
采用线性滤波器法中的自回归模型,模拟节点随机脉动风速时程,运用Matlab编程有效地模拟具有时间相关性、空间相关性的脉动风速时程。通过对模拟所得的双坡屋面节点风速时程的统计分析,显示了该算法具有较好的模拟精度和计算速度,可满足工程应用的要求。
The method based on the application of linear filters to sequences of random numbers is used. Artificial wind time speed series with outstanding time and space correlativity are implemented by programming Matlab. Statistical analysis results of the double-slope roof structure show that AR model is efficient in simulating nodal wind speed time series which can be applied to engineering with regard to the simulation precision and efficiency.
