Abstract: The problem of modeling hydro-elastic longitudinal oscillations in liquid fuel tanks by mechanical analogs is considered. It is necessary to provide the inertia and dynamic properties coincidence of a real structure and its computational model with mechanical analogs. Special attention has been payed to correct modeling of the external active forces, acting on the fuel tank with engine, when mechanical analogs are used. The proposed approach can be used in modeling of a ground static firing test when engine is mounted on the tank dome, and in dynamic load analysis of the advanced launch-vehicle reusable stages.

Keywords: dynamic response, load analysis, equivalent beam-like model, mechanical analogs, hydro-elastic modes, active forces.
