An attempt to determine the value of forces acting on the wheel while overcoming road unevenness

Driving on an uneven road often leads to tire and wheel damage. The article attempts to determine the values of forces when overcoming road unevenness. It has been assumed that there is a single unevenness on the road with a certain height that the vehicle runs over at different speeds. The effect of inequality and vehicle speed on the magnitude of individual forces was analysed. The stiffness of the tires was determined on the flat road and on the edge of the bump on the basis of the tests. The tire deflections were determined at the moment of hitting the road unevenness.
