In this paper under the condition of low gravity the characteristic of liquid forced sloshing for a circular cylined with two hemispherical ends were investigated. Firstly, the static shape of the liquid surface was analysed. And then, by using the expansions with characteristic functions, the frequencies and velocity potentials of liquid free vibrations were derived. The governing equations and boundary conditions were established for the forced vibrations of liquid under the transvers vibration of the container, and using the method of function expansions the velocity potential and the tolal force and moment eperted on the lateral wall were found. Finally, numerical results were obtained.
