This paper presents the results of numerical analysis and physical simulation of the vertical steel tank for usage in the vibration condition monitoring system. For purposes of the numerical analysis the tank is considered as the double steel cylinder consisting of the inner and outside shells. The discrete model of a tank is developed. The estimations of stress and deformation are obtained when the following vertical loads are exerting: weight of the fuel, weight of the tank roof and other structural elements or equipment. The physical model of a tank is used for physical simulation. The impulse responses of this model are measured and analyzed for different levels of tank filling. The methods of Prony and Steiglitz-McBride are used for estimation of the vibration damping factor which depends on the level of tank filling.
