Bus Handling Analysis and Experimental Validation Using the Multibody System Technique 2001-01-3966
This paper describes the modeling, experimental procedures and validation process used for a bus model in ADAMS/Car. It is described the bus subsystems which have been generated by ADAMS/Car templates. A comparison of experimental results and model simulation for an ISO lane change at 80 km/h and a sweep steer at 40 km/h with steering wheel imposed motion are made. Some of the quantities ilustrated are: steering wheel angle, lateral acceleration and yaw rate. Frequency domain analysis was made and the yaw rate and lateral acceleration gains and phases due to steering wheel angle were plotted. Finally, a comparison is made between ISO lane change with imposed motion versus a machine control (driver) with varying driver parameters.
