Abstract:The pipe theory is introduced into the flow-induced vibration research of a laminated plate-type structure. The mechanical model is set to describe the plate-type structure in potential flow. The dynamic equation is deduced based on Hamilton principle. The differential quadrature method is used to solve the differential equations. And the effects of various parameters on instability are investigated. The results show that the cantilevered model has the flutter over the critical velocity. And the parameters of the gap, mass ratio, gap asymmetrical parameter and velocity asymmetrical parameter have influence on the flutter velocity. But those have no effect on the instability mode in the range considered for the parameters .
