Calculation Assessment of Rolling Resistance Factor of Car Wheel

摘要

A calculation procedure of the factor of rolling resistance for a driving car wheel has been elaborated for a constant speed of inertia center. The method employs a simplified wheel model comprising a rigid disc, gas-filled shell and a thin viscoelastic layer. The method developed takes into account the presence of centripetal acceleration in the deformed layer points. The rated dependencies of the factor of rolling resistance on the speed of inertia center and inner pressure are compared to the results of a known empirical relation.
