| 摘 要： | 针对多维ＡＲ模型同时求解回归系数矩阵所有元素的一些不足之处，本文提出了混合回归模型。通过对某一高耸结构的分析，表明混合回归模型对脉动风的模拟是有效的，并人数值模拟角度验证了，对于线性结构，外激的各态历经性可保证响应的各态历经性。

| Abstract: | As muti dimensional AR model has some drawback in the procedures of solving all the elements of the regressive matrixes, the Hybrid Regressive(HR) model is proposed in this paper. Numerical examples show that hybrid regressive model is effective to the simulation of pulsating wind. From the viewpoint of numerical simulation, for linear systems, it is verified that the ergodicity of the external excitation can ensure the ergodicity of the structural response |
