The aeroelastic characteristics of tandem positioned two-dimensional elastic panels have been numerically investigated. High-fidelity Computational Fluid Dynamics and Computational Structural Dynamics (CFD/CSD) methods have been used to simulate the aeroelastic interactions between the panels. Moreover, a CFD-based reduced order model is established through system identification method for auxiliary analyses. The results indicate strong fluid-mediated interactions between the adjacent panels. At low supersonic speeds, affected by the self-sustained vibration of upstream panel, the downstream panel exhibits the characteristics of forced vibration state for some parameter ranges where the flutter should occur. Beyond these parameter ranges, the vibration frequency of downstream panel gradually departs from the wake flow frequency and coincides with the flutter frequency of its isolated state, exhibiting the characteristics of limit cycle flutter. At high subsonic speeds, the aeroelastic response of downstream panel has a stabilizing effect on the upstream panel, and increases the dynamic stability of the entire tandem panels system. The aeroelastic behavior of the adjacent panels may enlighten a new perspective on the flutter control of the shell structures.

串联定位的二维弹性板的气动弹性特性已进行了数值研究。高保真计算流体动力学和计算结构动力学（CFD / CSD）方法已用于模拟面板之间的气动弹性相互作用。此外，通过系统识别方法建立了基于CFD的降阶模型进行辅助分析。结果表明，相邻面板之间存在强烈的流体介导的相互作用。在低超声速下，受上游面板自身持续振动的影响，下游面板在某些应发生颤动的参数范围内表现出强制振动状态的特性。除了这些参数范围，下游面板的振动频率逐渐偏离尾流频率，并与其隔离状态的颤动频率一致，表现出极限循环颤动的特性。在高亚音速下，下游面板的气动弹性响应对上游面板具有稳定作用，并增加了整个串联面板系统的动态稳定性。相邻面板的气动弹性行为可能会启发人们对壳体结构的颤振控制有一个新的认识。
