【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更多还原
