摘要
首先分析了一种宽域平稳随机过程的特性 ,然后基于频谱表达方法并利用Kaimal风谱函数的特性 ,提出了一种模拟桥梁脉动风场的高效率方法 ;证明了采用本文方法模拟产生的脉动风场具有各态历经性 ,满足目标互相关函数 ;
The characteristics of a wide sense stationary random process were investigated in this paper. Based on the spectral representation method and Kaimal wind spectrum, an efficient stochastic simulation technique for wind turbulence field along the bridge span was proposed. The digitally regenerated turbulent wind speed processes are ergodic and comply with the target cross_correlation functions. A numerical example was illustrated.
