Hydropneumatic Suspension Efficiency in Terms of Teleoperated UGV Research

More often Unmanned Ground Vehicles (UGV) support or replace human in dangerous tasks performing. Usually this operations are realizing in hard conditions in rough terrain. UGVs effectively use determines its ability to obstacle negotiating, to reach high adhesion force, drawbar pull and extra longitudinal and lateral stability of UGV. Variety missions determining of use in UGVs reconfigurable and control suspension system. It is able to meet this requirement thanks to use hydropneumatic components in them suspension system. However currently it is very hard to developed characteristic of such a suspension systems. In literature there is no clear guidelines for suspension systems of teleoperated UGVs. This paper presents results of hydropneumatic suspension system research on heavy UGV.
