FLOW-INDUCED VIBRATION OF A PLATE-TYPE BEAM WITH ELASTIC SUPPORT

摘要

The flow-induced vibration of a plate-type beam structure with "pinned-spring" support is studied in this paper. Adopting the assumption of a viscous, incompressible two-dimensional flow, the partial differential equations of the structure are set up, and the Galerkin method and the Fourth-order Rung-Kutta method are employed to solve the partial differential equations. The critical flow velocity is obtained under certain structural and fluid parameters, then the effects of the varying parameters on the critical flow velocities are investigated.
