- The aspects related to the dynamic modeling of the mechanical properties of motorcycle tires following the practical application of research methods have been analyzed for many years. A test stand was constructed for the examination, and a mathematical model was proposed to calculate tire parameters. This study aims to develop the characteristics of the radial dynamic stiffness of a pneumatic tire depending on the pressure in the tire, speed of the beater simulating tire slipping onto a small obstacle lying on the road, and impact damping. The testing device was designed to simulate a sudden strike of a tire on a stiff foreign body lying on a road plane. The experiment was performed for three different values of air pressure in the tire, beater rate, and impact energy of the tested wheel. The dynamic radial stiffness of pneumatic tires decreased with increasing deformation speed and pressure. Presented in the paper research methodology can be an introduction to further, more complicated research, where will be taken into consideration factors such as wheel rotation, driving or breaking the wheel, friction, etc. The proposed methodology can be extended to assess the dynamic adhesion coefficient during tire impact loading.
