Dynamic Models for the Traction System of the Self-Propelled Machines

Abstract

The work presents a classification of traction systems as a function of structure, the systems being classified into: integrally mechanical-tractional systems–STIM, mechanical-hydrostatical tractional -STMH and integrally tractional hydrostatical systems STIH. Each structural model contains the main components from dynamic points of view: the thermical engine as the source of energy, the system of transmission of the traction, the system of movement formed of wheels with tyres or the of self-propelled equipment. For each structural model is the dynamic model to which dynamic analyses should be done by excitation accomplished by the road (the run away). The models allowed the author to analyse the dynamic behaviour produced by dislevels of the road, consistence of the road, adherence of the road, etc. The necessity of these models has been due to the study models of dynamic behavior and of traction systems comparison of different structures, mechanic, mechanic and hydraulic.
