Abstract

Keywords: flywheel, engine test bench, simulation, vehicle acceleration.

For the study of the vehicle’s behaviour there are widely spread the road tests and the roller bench. Obviously, both of them need the vehicle, but the advantage comes from the numerous measuring possibilities presented into a laboratory. Predicting of vehicle’s performance is one important step in the design process. By analyzing the operation of a vehicle during its life, the acceleration process is amongst the very sensitive regimes. A theoretical study of the transient phenomena of i.c.e. is very difficult. Consequently, it is imperative to perform experimental investigations.

The approach presented in this paper is specific to the MATLAB/SimulinkTM software. In order to validate the simulation’s results, the authors rely on experimental acceleration tests obtained on a flywheel engine test bench, concerning the third, fourth and fifth gear of the vehicle. The difficulty was to obtain some transfer functions able to reproduce the engine behavior on sudden accelerations. The purpose of this paper is the dynamic modeling and simulation of a vehicle during sudden accelerations. The tests were performed by the authors on the CNAM’s engine test bench, equipped with an inertia flywheel.
