摘　　要：采用CFD/CSD双向流固耦合算法研究平板结构的气动弹性耦合特性.首先,采用CFD/CSD算法计算平板结构的颤振临界速度,并与已有文献中的实验结果进行比较验证.然后,分别对简支和固支边界条件的三维平板结构进行气动弹性特性分析,计算不同约束情况下流场分布的变化和平板结构的位移响应.同时还考虑加肋和结构材质对平板结构气动弹性特性的影响.The two-way fluid-structure coupling algorithm, i.e. the CFD/CSD algorithm, is used to study the aeroelastie coupliing characteristics of plate structures in subsonic air flow. Firstly, the flutter critical velocity of the plate structure is computed employing the CFD/CSD algorithm. The results obtained by the CFD/CSD are verified by comparing with the experiment results in the open literature. Secondly, the aeroelastie characteristics for three-dimensional plate structures with simply supported and clamped edges are analyzed. The variation of flow field distribution and the displacement responses of the plate under different restricted conditions are clacu- lated. Meanwhile, the influences of the stiffener and structural material parameters on the aeroelastic eharacteris- rices of the plate structure are also considered.
