An Efficient Numerical Scheme for Evaluating the Rolling Resistance of a Pneumatic Tire

The viscoelastic effect of rubber material on creation of rolling resistance is responsible for ۱۰-۳۳% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are prone to considerable numerical oscillations. By adding the equivalent loads to static interaction of tire with the road, an efficient ۳D FE analysis is presented for evaluating the dissipated energy of a rolling tire. The results closely match the related experimental and numerical investigations.
