Natural and Forced Vibrations of Axisymmetric Structure Taking into Account the Viscoelastic Properties of the Base

The paper considers an inhomogeneous elastic system; axisymmetric construction with foundation and foundation. Investigations of the interaction of the structure with the base. To study the interaction of the structure with the base, a cylindrical base model cut from half space is used in the calculations. It is believed that the lower part of the base is stationary, and the side surface is free. The eigenfrequencies and vibration modes of the considered heterogeneous system are determined. The influence of the geometric and physico-mechanical parameters of the base on the dynamic characteristics of the structure is investigated, the problem of the natural vibrations of the heterogeneous construction-base system is solved.
