| 中文摘要: |
| 利用轮廓扫描测量系统和压力分布测量系统，研究不同品牌全钢载重子午线轮胎在不同充气压力下的轮廓以及不同充气压力和负荷下的接地压力分布及其对轮胎磨损的影响。结果表明：在不同充气压力下，胎冠处的轮廓变化很小，而断面宽度随着充气压力的增大而增大，当超过标准充气压力后，断面宽度基本不变；当轮胎负荷不变时，充气压力越大，轮胎应力越集中在胎面中间部位，平均接地压力也越大，胎面中间的磨损加快；轮胎负荷率达到120%时，标准充气压力仍足够承担负荷；轮胎负荷越大，磨损速度尤其是胎肩部位的磨损速度越快。 |
| 英文摘要: |
| The contour scanning measurement system and the pressure distribution measurement system were used to study the profiles of different brands of truck and bus radial tires under different inflation pressures and the distribution of ground pressure under different inflation pressures and loads and their effects on tire wear.The results showed that under different inflation pressures，the profile change at the crown was small，and the cross-section width increased with the increase of the inflation pressure.After exceeding the standard inflation pressure，the cross-section width was almost unchanged.When the tire load remained unchanged，the greater the inflation pressure，the more concentrated the tire stress was in the middle of the tread，the greater the average grounding pressure，and the faster the wear in the middle of the tread.When the tire load rate reached 120%，the standard inflation pressure was still sufficient to bear the load；the larger the tire load，the faster the wear rate，especially the wear rate of the shoulders. |
