VIBRATION OF CYLINDERS PARTIALLY-FILLED WITH LIQUIDS

A mathematical model of a coupled cylindrical shell-fluid dynamic inte raction problem based on an axisymmetric finite element analysis is pr esented. The dynamic solution of the problem is separated into axisymm etric and nonaxisymmetric behaviors and a method is presented for the nonaxisymmetric transient response analysis. If is employed to estimat e the natural frequencies of the cylinders partially filled with water . The theoretical predictions are compared with the experimental resul ts and it is shown that there eixsts a good correlation between the tw o sets of results.
