Opis:
Issues of driving stability of special-purpose vehicles result from engineering compromise between need of fulfilment of operational requirements and traction correctness of a vehicle. Especially, it concerns a motion in dynamic conditions with presence of high transverse accelerations. The paper comprises description and analysis of motion stability test results of a special-purpose two-axis vehicle with kerb mass of above 12 ton, with 4WD drive system, on a circular path drive and single line-change. One described methodology of the testing, used testing-measuring instrumentation, and distribution of the instrumentation in tested vehicle. It have been included a brief descriptions of the implemented instrumentation and method of acquisition and processing of the measurement data. One has tested a vehicle with highly located and considerably moved rearward centre of gravity. Such distribution of axle loads resulted from necessity of fulfilment of operational requirements of the vehicle. In the paper are presented test results performed for nominal and reduced with 20% tyre pressure. There were analyzed runs of lateral accelerations and axle slip angles in assumed condition of motion. One formulated general conclusions on stability characteristics for such type of vehicles.

Opis:
The use of physical models of vehicles, at a scale allows them to be used when measuring the behavior of the full-size vehicles. The characteristics of the various systems and their impact on the dynamics of motion of the vehicle can be determined during stand tests or simulation and confirmed during testing of vehicles on test tracks. Testing vehicles built in small series, oversized or performed individually are conducted infrequently or not at all. In such cases, the alternative may be conducting tests of vehicles carried out at a scale. Research may be conducted in the boundary conditions (which could lead to loss of stability or overturning of the vehicle) impossible to achieve during testing of actual vehicles. They are particularly useful for assessing the stability of vehicles, the impact of the solutions or actions of a driver assistance system. Conducting research vehicles at a scale for the assessment of full-size vehicle must meet the criteria of similarity in the study of physical models of vehicles. One of the major issues is interaction of wheels and road. This article describes the results of wheels interaction with the road for tires with different characteristics used in the mobile model of the car and on the actual vehicle. The aim of the study was to prepare reference material to determine the correlation between the characteristics of the tire model and the full-scale tires. This will allow for made adjustment resulting from the impact of the characteristics of the tires on the motion dynamics of comparable cars especially in the curvilinear motion.
