The paper is devoted to investigating a roller testing unit with a closed circuit for testing wheeled vehicles. A distinctive feature of the unit is its rigid connection between cylindrical surfaces which causes a kinematic mismatch between their angular velocities of rotation. The authors consider the power and kinematic interaction of a vehicle wheel with cylindrical surfaces in a new type of testing units, and find experimentally an interaction between the power and kinematic parameters of the contact between a tire and a cylindrical surface in the driving mode. A mathematical model of the testing unit with a closed circuit is developed to analyze the behavior of power flows at various mismatching transmission ratios. Therefore, some recommendations for choosing reasonable values of transmission ratios for various types of testing for wheeled vehicles are given. The proposed testing unit provides a constant value of skidding, which expands the diagnostic capabilities of testers of this type. It makes possible to determine the elastic and traction qualities of tires in all running modes (driven, driving, or braking), to carry out running, short time and braking testing for vehicles, to test tires for wear, heat resistance and strength, to carry out shafting tests of engines with and without loading, to test the turning mode with accelerated testing of differentials, and to simulate different ground conditions under wheels by providing different kinds of skidding.

The problems of kinematics and mechanics of interaction of a rigid metal wheel with a deformable base on basis of the theory of instant tipping of a lever are considered. Calculated dependences are presented to determine the main indicators of interaction of the wheel with the supporting surface: strength, speed and power. It is established that rolling of the drive wheel, in comparison with the follower wheel, leads to an increase in the depth of the track, and rolling resistance force decreases in this case.

Introduction. Farmers make extensive use of two-wheel tractors equipped with traction and drive interchangeable units. Two-wheel tractors are required to move evenly with minimal slip of the drive wheels on the soil. The tractive force on the drive wheels of the tillage unit is the decisive power factor in this case. An objective traction force value can be measured only by carrying out experimental studies. Materials and Methods. To determine the traction force on the drive wheels of the twowheel tractor, the design of the experimental stand was proposed and substantiated (RF patent for useful model No. 188610 “Movable module of the test stand”), and a methodology for planning and conducting a multifactor experiment to determine the traction force was developed. Results. As a result of the laboratory tests the calculation dependencies of the tractive force on the drive wheels of the Neva MB23-MultiAGRO Pro two-wheel tractor were obtained. Soil conditions, design and technological parameters, operating modes of the two-wheel tractor, and rolling resistance forces were taken into account. Discussion and Conclusion. The use of the developed regression models of the traction force under the condition of ensuring uniform movement with the minimum permissible slipping of the driving wheels of the two-wheel tractor on the soil will allow obtaining the permissible values of the two-tractor motion speed and form the zones of its most effective functioning.
