Simulação do sistema de transmissão de potência em tratores de esteiras de borracha.

Abstract

A mathematical model was implemented to simulate the performance of the rubber-tracked tractors. In this model, the power transmission system was simulated including sub-models for the engine, gear box, differential system, hydraulics steering system and interface soil/tracks. Field tests, by using a Challenger 75 tractor made by Caterpillar, were done to validate the implemented model. Comparing the simulated results to the experimental data it was concluded that the model predicted well the torque and speed of different components of the power transmission system of the tractor.
