Lateral response formation process between an elastic tire and a supporting surface when a slip angle wheel crosses a single irregularity

The article presents the results of an analytical and experimental study of R_Y lateral response formation between the elastic tire and the support surface when the wheel with the slip angle δ moves over a single irregularity. In this paper bench methods of experimental study of R_Y lateral response formation process between the elastic tire and the support surface, when the wheel with the slip angle δ moves over a single irregularity, are used. The experiment results have been obtained in bench conditions on a special test bench developed by the scientists of the Department of Automobile Transport of Irkutsk National Research Technical University. The results of experiments and calculations are presented in the form of graphs. The results obtained allow us to assert that in the research of R_Y lateral response formation between the elastic tire and the support surface, when the wheel with the slip angle δ crosses a single irregularity, it is necessary to consider the unsteady mode of wheel rolling and take into account the fluctuations of individual tire parts.
