Based on the characteristics of the membrane structures , wind - induced nonlinear coupling dynamic response analysis which can be applied to closed membrane structures is developed and the added air mass the pneumatic stiffness and the acoustical damping of the closed membrane structures are deduced . applying the method to an aeroelastic model of wind tunnel test , the displacement the velocity and the acceleration of corresponding prototype structure in time domain are obtained
本文针对封闭式薄膜结构和敞开式薄膜结构推导了全新的非线性流固耦合风振响应公式，其中耦合因素包括附加空气质量、气承刚度和声致阻尼以及相对运动速度，并将此理论应用于一气弹模型的计算，获得了位移、速度、加速度时程以及加速度均方根。
