REPRODUCIBILITY OF THE VEHICLE VERTICAL MOTION BY KIT DRIVING SIMULATOR USING THE ACTUAL MEASUREMENT DATA

Abstract

We considered the driving simulator that was suitable for road surface evaluation and added new functions to a conventional driving simulator. Kitami Institute of Technology driving simulator (KITDS) has two distinct functions. As the 1st function, it makes possible to generate vehicle motions traveled over any pavement surfaces using measured profile data. As the 2nd function, it enables to reproduce the various vehicular motions using measured 6 degrees of freedom (d. o. f) vehicle motion data. The driving simulator offers advantages in high-security, high-repeatability and economical efficiency. In this study, In order to verify the reproducibility of a vehicle motion by the motion platform of KITDS, we reproduced the theoretical signal and an actual vehicle motion. Additionally, we compared input vibration with the reproduced vibration. In conclusion, the vertical acceleration that is an index related to the ride comfort showed high reproducibility in the frequency band of 0.4 to 10Hz.
