| Abstract: |
| The 205/55R16 electric vehicle tires were selected for finite element simulation analysis to study the influence of the belt widths on the footprints，cornering stiffnesses and aligning stiffnesses of tires.The results indicated that，the footprint minor axis length did not change significantly with the increase of the belt width，the footprint major axis length increased with the increase of the belt width.The footprint area increased with the increase of the belt width，but the increase was relatively small.The influence of the belt width on cornering stiffness of the tire exhibited different trends depending on the air pressure and load.The alignment stiffnesses of the tires with different belt widths decreased with increase of the air pressure and increased with increase of the load，the higher the load of the tire and the lower the air pressure，the greater the aligning stiffness. |
