SOFTWARE FOR VEHICLES PROPULSION SYSTEMS CALCULATION 2007-01-2618

The objective of this work is to elaborate a software to determine characteristics such as torque, power and speed for transmission relation and rotation. The vehicle transmission is a component that is responsible for transmitting the motor power to drive vehicle wheels. The chemical energy (fuel) in power train is transformed in mechanical energy and in the most used cases are: internal combustion motors with Otto cycle and as well, as the Diesel cycle. The whole power train works on a certain rotations band, which is limited by the motor rotation. The dynamic condition of a vehicle is obtained with the resistance equation movement (rolling and drag). In other words, through it occurs the force balance in transmission with the need to force in the traction wheels, usually well known with resistance to the movement. The software elaborated in Excel was validated with experimental results. In that order, with the elaboration of the software for characteristics determination of propulsion of automotive vehicles, that reduces significantly time to the calculations accomplishment.
