| 摘 要： | 论文从理论分析和实验研究两方面对轴向流中悬臂柔性板流固耦合动力特性作了研究.基于板的轴向不可延伸假设,采用Hamilton变分原理,推导了轴向流中悬臂板非线性运动偏微分方程,通过面元法计算悬臂板上下面压力差.采用伽辽金法离散该非线性运动偏微分方程,通过无量纲化物理参数,研究了系统无量纲颤振临界速度,给定流速下悬臂板末端...

| Abstract: | Theoretical and experimental studies are devoted to investigate the dynamical behaviour of cantilevered flexible plates in axial flow.Nonlinear partial differential equations of motion based on the inextensibility assumption are derived from Hamilton's principle for this kind of plates.The pressure difference between the two sides of the plates is calculated with a panel method.The partial differential equations governing the movement of plates are discretized with the use of the Galerkin method.The non-dim... |
