【摘要】:基于多變量非高斯隨機(jī)過(guò)程間的相關(guān)性,將發(fā)展的單變量非高斯過(guò)程的非迭代算法擴(kuò)展至多變量非高斯過(guò)程的模擬.通過(guò)多變量高斯過(guò)程的相干函數(shù)來(lái)考慮多變量非高斯過(guò)程的互相關(guān)性,建立多變量非高斯過(guò)程的非迭代模擬算法.多變量非高斯風(fēng)壓的數(shù)值模擬表明:非迭代模擬算法能有效地模擬低、中、高斜度的多變量非高斯過(guò)程.
[Abstract]:Based on the correlation between multivariable non-Gao Si stochastic processes, the developed non-iterative algorithm for univariate non-Gao Si processes is extended to the simulation of multivariable non-Gao Si processes. Based on the coherence function of multivariable Gao Si process, the non-iterative simulation algorithm of multivariable non-Gao Si process is established by considering the interrelation of multivariable non-Gao Si process. The numerical simulation of multivariable non Gao Si wind pressure shows that the non iterative simulation algorithm can effectively simulate low, medium and high slope multivariable non Gao Si processes.
