Methodology for Analysis of Dynamic Behaviour of Wheel Loaders

Rolling Resistance - an overview | ScienceDirect Topics

When a loaded wheel and tyre is compelled to roll in a given direction, the tyre carcass at the ground interface will be deflected due to a combination of the vertical load and the forward rolling effect on the tyre carcass (Fig. 8.10).The vertical load tends to flatten the tyre's circular profile at ground level, whereas the forward rolling movement of the wheel will compress and spread the
