Dynamics of electromechanical drive of suspended timbertransporting rope system

Dynamic loads of drive of suspended timbertransporting rope system with an electric motor are investigated. Developed a dynamic model of the electromechanical drive considering the changing of the electric motor’s moment during start-up and the resistance force moment. The changing of the resistance force moment is expressed through the changes in tension force of the pull-bearing rope systems in various manufacturing operations. In determining the moment of inertia of the drive drum is accounted multi-winding of rope. Research on dynamic load of system elements are made with the taking into account the influence of torsional stiffness of system parts and lifting capacity of the suspended timbertransporting rope system.
