| Abstract: | In this paper an investigation of the dynamic characteristics of liquid sloshing in an ellipsoidal tank for a launch vehicle is described. The equivalent mechanical models of liquid sloshing are derived using a scale model test under a 1-g acceleration. The first equivalent mechanical model parameters are estimated by the parameters identification technology, and are compared with the analytical results. Observations and measurements of the nonlinear effects in the sloshing test are described. |
