AR model in linear filter theory is adopted to simulate pulsant wind. Combined with some typical cable-membrane structures, research on self-vibration of the structure has been conducted. Based on the previous work, the influence caused by the vertical wind component on the membrane roofs has been analyzed in time domain. It includes the vibration laws of the structure under separate horizontal wind component, separate vertical wind component and the collective horizontal wind component and vertical wind component. Significant conclusions have been drawn from the analysis.

然后本文采用线性滤波器法中的AR模型对风速场进行了模拟；之后又结合典型的张拉索膜结构研究了膜结构的自振特性；在此基础上，本文研究了索膜结构在竖向脉动风影响下的风振响应特性，其中分别研究了张拉索膜结构在单独水平风，单独竖向风以及水平风和竖向风共同作用下的振动规律，得出了有关重要结论。
