The efficiency of a skid-steer, all-wheel drive, multiple-axle vehicle with a hydrostatic drivetrain equipped with low-speed motors when it operates on soft terrain was studied. A flow divider enables a single pump to simultaneously power more than one motor circuit with different pressures in each. It prevents kinematic discrepancy and improves vehicle mobility. There are two types of flow divider: spool type and gear type, where each type has its own set of performance characteristics, such as flow range, pressure drop, accuracy and application parameters. In the present work, the influence of the characteristics of both types of flow divider on overall vehicle driveline efficacy is described.

Heavy-wheeled vehicles with articulated hydraulic steering systems are widely used in construction, road building, forestry, and agriculture, as transport units and tool-carriers because they have many unique advantages that are not available in car steering systems, based on the Ackermann principle, such as—high cross-country mobility, excellent maneuverability, and high payload and lift capacity, due to heavy axles components. One problem that limits their speed of operation and use efficiency is that they have poor directional stability. During straight movement, articulated tractors’ deviate from a straight line and permanent driver correction is required. This limits the vehicles’ speed and productivity. In this study, we describe a driver-aid system concept that would improve the directional stability of articulated vehicles. Designing such a system demands a comprehensive knowledge of the reasons for the snaking phenomenon and driver behaviors. The results of our articulated vehicle directional stability investigation are presented. On this basis, we developed models of articulated vehicles with hydraulic steering systems and driver interaction. We next added the stabilizing system to the model. A simulation demonstrated the possibility of directional stability improvement.

This paper presents issues of hydrostatic drivetrains applied in slow-moving transport terrain vehicles. Short description of such a vehicles was described. Next efficiency of hydrostatic drivetrains and main factors which has influence on its efficiency was discussed. It was characterized two types of hydraulic components efficiency: volumetric and hydro-mechanic. They have detrimental effect on power loses in hydrostatic drivetrains. In final part of the paper efficiency of few hydraulic motors in the same load conditions was compare.

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.

Currently led military operations (Iraq and Afganistan) have shown that one of the biggest threats for vehicles moving in convoys are Improvised Explosive Devices. On the basis of experiments, it was found that there are not such structures which are completely resistant to explosion. The paper describes the concept for arms of suspension system with specially reduced construction node which undergo a controlled destruction at the time of detonation. Designing the target elements requires tests in order to determine the service load for suspension system..

Unmanned ground platforms are increasingly used to perform tasks under direct threat to the operators life and health. Separating an operator from a controlled machine places high demands to its steering system. The requirement of reliability put to such platforms in terms of potential threats makes their steering systems being very precise controlled and tested at the stage of construction. The key element in the steering process of unmanned ground platforms are surroundings display systems which determine the success of conducting rescue operations. This paper presents an unmanned ground platform controlled by remote operator and describes some of the functionality tests of the remote control system.
