考虑了亚音速流中面板的大偏转,特别是完全夹紧的冯卡门板,考虑了板丝的旋转惯性和(温和的)结构阻尼。该面板被认为嵌入到包含线性亚音速势流的正半空间的边界中。尽管缺乏与线性动力学生成器相关的自然耗散性,但解决方案是通过半群方法构造的。然后,通过显式的 Neumann-to-Dirichlet(下洗至压力)流动求解器,将流-板动力学简化为板的记忆型动力系统。对于非保守板块动力学,通过 Lyapunov 和最近的准稳定性方法明确构造了全局吸引子。最后,结果表明,通过吸引子的紧致性和耗散积分的有限性,所有轨迹都强烈收敛到稳态集。
The large deflections of panels in subsonic flow are considered, specifically a fully clamped von Karman plate accounting for both rotational inertia in plate filaments and (mild) structural damping. The panel is taken to be embedded in the boundary of the positive half-space incontaining a linear, subsonic potential flow. Solutions are constructed via a semigroup approach despite the lack of natural dissipativity associated with the generator of the linear dynamics. The flow–plate dynamics are then reduced—via an explicit Neumann-to-Dirichlet (downwash-to-pressure) solver for the flow—to a memory-type dynamical system for the plate. For the non-conservative plate dynamics, a global attractor is explicitly constructed via Lyapunov and recent quasi-stability methods. Finally, it is shown that, via the compactness of the attractor and finiteness of the dissipation integral, all trajectories converge strongly to the set of stationary states.
