EXPERIMENTAL RESEARCH OF DYNAMIC PARAMETERS OF A TIRE FOR HIL-TESTING OF VEHICLE ACTIVE SAFETY SYSTEMS

This publication presents the specialists’ experience of Nizhny Novgorod State Technical University n.a. R.E. Alekseev (NNSTU) in field studying friction-rolling an automobile wheel on asphalt surface. Adequate mathematical reproduction force reactions that occur contact patch plays a significant role modeling vehicle dynamics. Since fundamental description this interaction is difficult, engineering practice empirical method has become popular, which consists obtaining experimental data array with its subsequent trigonometric approximation and systematization. NNSTU specialists have developed test methodology carried out full-scale tests using specialized road tire trailer bench. The experiment was dry pavement coefficient adhesion about 0.4–0.8 at ambient temperature 20 °С. resulting processed presented form digital model PAC 2002. maximum discrepancy between theoretical absolute value doesn’t exceed 5 %.
