This paper deals with a theoretical analysis of dynamic instability of vibrations induced in a flexible weir subjected to fluid discharge over the weir top. We formulate the equation of motion for the coupling vibration of a flexible weir and sloshing liquid contained in upper and lower tanks by taking into accout the time lag generated by the fluid travel from the top of the weir to the surface of the liquid contained in the lower tank. The energy of the vibration of the weir produced by sloshing and dissipation energy are evaluated to find the instability conditions in terms of discharge height. The instability conditions are clarified with respect to important parameters of this fluid structure coupling system and are compared with experimental results.
