Abstract

This project focuses on modeling, simulation and validation of a reduced scale vehicle dynamics model. Research in the area of vehicle dynamics often requires the mathematical model to represent the vehicle dynamics behavior with the help of virtual simulations but the prediction by simulation might differ from the actual vehicle dynamics behavior. Thus, validation of the simulation results with vehicle dynamics simulation software or by experimental is required. However, the high development cost and time to validate the simulation results with full scale vehicle testing was an obstruction to researchers. In order to reduce the development cost and time, reduced scale vehicle was introduced in this project. A 8 degree of freedom vehicle dynamics model was developed to represent the dynamics behavior of reduced scale vehicle. Besides, a reduced scaled instrumented vehicle is developed and used as a vehicle dynamics testbed to investigate the full operational range of reduced scale vehicle handling. Wireless sensing system was used to capture vehicle response wirelessly. Finally, the results obtained from the experimental of a scale vehicle with J-turn test was represent the actual behavior of reduced scale vehicle and these results used to validate the vehicle dynamics model developed. The vehicle model developed could be used to study dynamic behavior of the vehicle and for controller strategies design and implementation without the need to conduct experiment.
