Abstract:

One of the most urgent tasks related to improving the efficiency of dynamic studies of modern machines drive systems represents the task of developing such dynamic models of mechanical systems of drives (mechanical transmissions) that together with the consideration of specific features, are effectively used for subsequent studies of dynamic processes in purely mechanical as well as in electro- and hydromechanical drives. In this paper, is proposed an original methodology for constructing of dynamic models, taking into account the elasticities of the links as well as the nonlinearities determined by the gaps and frictional forces.

Keywords: modeling of dynamics; backlash connection; moment of inertia; differential equation; harmonic linearization; nonlinear constraint
