Abstract

This article presents experimental and theoretical research of a rotor system with variable inertia moment. A mechanical system model was designed using SimMechanics toolbox in Matlab Simulink. Experimental and simulation results of the test rig are presented in the article. In order to compare the obtained results, model parameters were chosen based on actual parameters of the test rig. Results obtained from the analysis of the developed dynamic model enable to propose a rotor design with a variable inertia moment which, under certain initial conditions, would maximally reduce forces exerted on bearings during the operation.
