摘　　要：本文基于固定界面模态综合法建立非线性结构模型,基于ZONA方法及最小状态法获得非线性结构的非定常气动力,最后开展了间隙非线性结构的气动弹性仿真,分析了不同初始扰动及飞行速度下结构的气动弹性响应,该成果可用于其他形式集中参数非线性结构的气动弹性仿真分析,具有一定的研究价值。A nonlinear structure model is established based on the fixed-interface modal synthesis method. The unsteady aerodynamic force of nonlinear structure is obtained based on ZONA7 method and Minimum-State method. The aeroelastic simulation of centralized nonlinear structure is carried out. And the aeroelastic response of structures under different initial disturbances and flight speeds is analyzed. The results can be used to analyze the aeroelasticity of other forms of nonlinear structures of centralized parameters.
