Modélisation et simulation dynamique d'un véhicule urbain innovant en utilisant le formalisme de la robotique

Abstract : Modeling and simulating are fundamental tools to develop new vehicles. The aim of this thesis is to model and simulate a urban narrow tilting car whose structure contains closed mechanical chains. Hence the goal is to build a physical model more precise and realistic than the bicycle model or quarter vehicle model used usually for some control purposes. The modeling approach is based on the modified Denavit&Hartenberg description, commonly used in robotics, by considering the vehicle as a multi-body poly-articulated system whose the terminal links are the wheels. This description allows calculating automatically the symbolic expression of the geometric, kinematic and dynamic models, by using robotics techniques and a symbolic software package named SYMORO+. The dynamic model is calculated recursively thanks to the Newton-Euler algorithm. Simulations of different dynamical model of vehicles have been performed, analyzed and compared. They validate in some sense the modeling methodology presented as an efficient way to get realistic model of non-standard vehicles.
