The tyre characteristics of the physical model used to investigate the lateral stability of a vehicle

This paper presents a comparison of the characteristics of the tyres of a full-size vehicle with the tyres of a physical model scaled 1:5. This is a continuation of studies on the use of a scaled vehicle to test the stability of a vehicle. The results presented are based on analysis of a scaled vehicle and a full-size vehicle on a stand and during road tests. Tests were carried out involving manoeuvres based on the ISO standard. The effects of the differences in the construction of the tyres of the scaled vehicle and their impact on the tyre characteristics and its behaviour during testing were compared. This paper presents the results of a comparison of selected parameters of motion for a real vehicle and for a mobile scale model. These tests allowed a statement to be made about the suitability of the used tyres and the entire physical model for lateral stability analysis of a full-size vehicle.
