On the dynamic behavior of agricultural tires

The dynamic behavior of vehicles which are equipped with pneumatic tires depends, to a degree, on the properties of the tire. Therefore, road handling and comfort are also affected by tire characteristics. When the inflation pressure is reduced one obtains a softer “spring”. The dynamic spring coefficient C_dyn increases with increasing rolling speed. Damping coefficient k is related to the excitation frequency by a power function. This function shows a sharp negative slope for low velocities. These conclusions apply to the tire types and test conditions described in this paper.
