| 中文摘要: |
| 选取205/55R16电动汽车轮胎进行有限元仿真分析，研究带束层宽度对轮胎接地印痕、侧偏刚度和回正刚度的影响。结果表明：接地印痕短轴长度随着带束层宽度的增大没有明显变化，长轴长度随着带束层宽度的增大而增大；接地印痕面积随着带束层宽度的增大而增大，但增幅较小；带束层宽度对轮胎侧偏刚度的影响受气压和负荷的影响而表现出不同趋势；不同带束层宽度的轮胎回正刚度均随气压的增大而减小，随负荷率的增大而增大；轮胎负荷越大、气压越小，回正刚度越大。 |
| 英文摘要: |
| 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. |
