The footprint is the <br>particular method to achieve the contact patch between a tire and pavement. The flat surface is often equipped <br>to support a pressure measurement film which is pressed by the tire tread. This derivative patch illustrates <br>characteristic seems the probable result to predict tire performance. Practically, the contact patch happens by <br>the rolling tire. To understand the patch characteristic, the contact patch between the rolling tire and pavement <br>was studied. The 3D finite element model of solid tire which pressed on three different surfaces was developed. <br>The experimental footprint on the flat surface was carried out to validate the finite element model. The contact <br>patch of solid tire tread on the drum surface was investigated to discuss the effect of supporting floor under <br>various testing method. The stress distribution in the solid tire model is the exceptional criteria to clarify the <br>contact patch on the road. The developed models will be used to design the tire tread and pavement in the future <br>work.</p> ER -
