摘要
A new simplified model for the application of a shallow cylindrical tuned liquid damper (TLD) in structural vibration control is presented in this paper. The dynamic properties of a shallow liquid in cylindrical containers subjected to forced horizontal oscillation are analysed directly from the continuity and momentum equations of fluids. Following some practical assumptions, the nonlinear partial differential equations describing the wave movement of a shallow liquid in cylindrical containers is established and a numerical procedure for the solution of these equations is proposed using the finite element method. The formula for determining the control force provided by the shallow cylindrical TLD is presented and the effect of several parameters on the control efficiency of a shallow cylindrical TLD controlled structure under wind action is investigated.
