Hydropneumatic suspension efficiency in terms of the teleoperated unmanned ground vehicle tests

Unmanned Ground Vehicles (UGVs) are increasingly supporting or replacing humans in performing dangerous tasks. Mostly these are activities carried out in unfavourable conditions, in very rough terrain. Efficient use of a UGV requires it to feature considerable ability to negotiate terrain obstacles, develop high traction and drawbar pull and a high UGV stability. The variety of missions performed using UGVs entails the need for them to incorporate reconfigurable controlled suspension systems. This can be achieved through the use of hydropneumatic components in their suspension systems. The difficulty in this respect is suitable shaping of the characteristics of such systems. In particular the lack of clear guidelines available in the literature for suspension systems in teleoperated UGVs. This paper presents the results of tests on a hydropneumatic suspension system on the example of a heavy UGV.
