“…The interior of the cockpit is suchlike to a vehicle (Figure 3(a)), 1 making this set of details increase the immersion of the driver in driver-in-the-loop simulations. 16 Regarding the SIM Center simulation robot structure, it is composed of a hexapod and a tripod (Figure 3(b)). 32 While the hexapod with its 6 degrees of freedom allows the movements of roll, pitch, and vertical translation, the tripod has 3 degrees of freedom to reproduce longitudinal translation and yaw motion.…”

Given the increasing use of virtual simulation in automotive vehicle designs, the correlation of virtual models is a fundamental part of the process. The present work seeks to develop a methodology for the development of virtual vehicle dynamics models correlated with kinematics and compliance (K&C) parameters for use in a real-time vehicle dynamics simulator. Aiming this and with the aid of an SPMM 5000e to obtain data from the physical vehicle and from the ADAMS/Car and VI-CarRealTime (VI-CRT) software to the development and simulation and from MATLAB to the correlation, a multibody virtual model correlated in K&C to a hatchback car, with McPherson strut and twist-beam front and rear suspensions, respectively, is developed. At the end of the work, it was observed that the correlation between the virtual model and the test vehicle was found successfully and that, therefore, the virtual simulation allows to find reliable results regarding the vehicle’s suspension and steering system behavior. Subsequently, with the tests carried out with a driver in a VI-Grade DiM 150, a real-time driver-in-the-loop simulator with 9 degrees of freedom (DOF), the model and thus the methodology is validated through the steering ratio analysis: The lateral acceleration analysis in the vehicle’s center of gravity in different maneuvers allowed to observe that the model with higher steering ratio requires greater steering wheel angle values about the model with the lowest steering ratio so that the same maneuver is performed.
