✦ Synopsis

The natural frequencies of liquid in a liquid-"lled cylindrical rigid tank without and with ba%es are evaluated. An annular plate is used as a ba%e, which is "tted to the inner periphery of a cylindrical tank. Both rigid and #exible ba%es are considered. Finite elements are used to discretize both the liquid and the structural domain. The slosh frequencies of liquid are computed for di!erent dimensions, thicknesses and positions of ba%es, both rigid and #exible considering the circumferential wave number as one. The axisymmetric and other asymmetric modes are not studied. The results obtained for rigid ba%e case are comparable with the existing results. The coupled vibration frequencies of the tank}#exible-ba%e system are computed considering the e!ect of sloshing of liquid.
