| ABSTRACT |
|
In this study, a methodology to build a new integrated ride and handling model is presented based on the Lagrangian method in terms of quasi-coordinates. The governing equations are derived considering the interaction between the ride and handling systems, Euler motion of the frames attached to the wheels and body, the load transfer among the wheels, and the variation of speed in longitudinal direction. The developed model is validated using ADAMS/Car for different maneuvers. In addition, a non-dimensional factor called coupling factor is introduced to study the coupling among different DOFs of the dynamic system. The results of the current study confirm the accuracy of the developed dynamic model for the simulation of the vehicle motion in comparison with the ADAMS/Car simulations and the models available in literature. The coupling factor is confirmed as an indicator parameter to demonstrate the advantages of the developed model over the existing dynamic models. |
