ALGORITHM FOR PLOTTING THE POWER AND TRACTION CHARACTERISTICS OF THE MOTOR VEHICLES

Abstract


The knowing of the resistance to advance is needed to assess the vehicle performance. The size of the drag forces and the powers necessary for their overcoming is influenced by their movement conditions and by the constructive parameters of the vehicles. The resistance to advance of the vehicles, the powers and forces at the driving wheels, for various situations of exploitation considered are evaluated by developing of a numerically MathCad model that gives the results with graphic interpretation and that takes into account of the various travel regimes, the gear, geometry, nature and the state of the road, etc. Thus, it can be identified the gear ratios that can be used in different operating situations of the the motor vehicle.

Key words: vehicle, drag resistance, self propelled, dynamic performance, modeling
