PREVIEW CONTROL OF HIGH MOBILITY TRACKED VEHICLE SUSPENSIONS BASED ON A RIDE QUALITY

Abstract

The role of the suspension system in tracked vehicles cannot be overestimated because the driving and running conditions of such vehicles are very severe. It reduces the vibration and shock that are generated by road profile in running conditions. As the tracked vehicle’s running speed is increases, more undesired vibration could be generated by the road profile particularly in the case of field running. Because excessive vibration can harm the operational ability of crewmen and stability of complex equipments, the maximum running speed is limited. In this study, we evaluate the performance of the preview control system based on the ride quality which is estimated from the acceleration of the driver position. Computer simulation is used to analyze that by for several profiles.
