Flexible toothed wheel coupling dynamics and failures

Abstract

Theoretical and experimental research of dynamics of rotating system with toothed wheel coupling and causality of elements failures was provided in this article. Modeling of flexible rotating system with nonlinear elements was design using FEM. Simulation results of dynamics model were accented in the vibration displacement values plots versus time and in the vibration displacements spectrum of the coupling elements. Experimental testing is based on rotating system bearings housings absolute vibration measurements and shafts relative vibration displacements and positions changes inside the journal bearings. Modeling and simulation data together with experimental testing in situ of rotating system supported to run more sophisticated coupling model and to design more reliable flexible coupling.
