Theoretical and Experimental Research of Oscillations with Excitation by an Elastic Element

The method of research of mechanical system oscillations with excitation by an elastic element using the developed automated laboratory complex is presented. The article describes the complex, the design of its electromechanical unit where the oscillation excitation is simulated, and the theoretical basis of the electromechanical unit operation. It also presents the methodology of the oscillation research and plotting the calculated and experimental amplitude-frequency (AFC) and phase-frequency (PFC) characteristics. It is shown that the present complex can be used when modelling the operation of units of real industrial facilities, and recommendations for such application are given.
