| 中文摘要: |
| 对SUV轮胎胎冠异常磨损机理进行研究及改善。胎冠异常磨损产生的根本原因是纵向花纹块（RIB）刚度在胎冠上面内外侧分布不对称以及胎冠中间RIB刚度相对于RIB2（从中间往外第2条RIB）明显过大或过小；RIB刚度分布呈“W”状，即中间RIB大于RIB2但小于最外侧RIB有利于改善胎冠异常磨损，依据此形状调整RIB后，轮胎没有出现异磨现象，整体磨耗均匀，达到了改善轮胎胎冠异常磨损的效果。 |
| 英文摘要: |
| The mechanism research and improvemente of abnormal wear for SUV tire crown were completed.The fundamental cause of tire crown abnormal wear was taht，the RIB stiffness distribution asymmetry of inside and outside on the tire crown and the middle RIB stiffness relative to the RIB2 （the second RIB which from the middle to outward）obviously too big or too small （in the case of a total of 5 RIBs）.Patterned RIB stiffness distribution was the W shape，namely the middle RIB was greater than the RIB2 but less than the most outward RIB，that was in favor of improving abnormal wear for SUV tire crown.Throuth adjusting pattern RIB according to this shape，the abnormal wear phenomenon of tire did not appear，the overall wear was uniform，and reached the effect of improving the abnormal wear of tire crown. |
