| 中文摘要: |
| 研究全钢载重子午线轮胎滚动阻力与胎面胶性能的相关性。结果表明：全钢载重子午线轮胎低滚动阻力指数与胎面胶硬度指数、拉伸强度指数和拉断伸长率指数没有相关性，与回弹值指数疑似相关，与300%定伸应力指数有强相关性；与低损耗因子（tanδ）（20和100 ℃）指数疑似相关，与低tanδ（60 ℃）指数的相关性很好；与弹性模量指数和低粘性模量指数没有相关性。胎面胶的tanδ（60 ℃）可作为轮胎滚动阻力的代用性能，低tanδ（60 ℃）指数修正因数为1/5，即胎面胶tanδ（60 ℃）减小0．1，轮胎滚动阻力下降16.4%。 |
| 英文摘要: |
| The correlation between rolling resistance and tread compound properties of truck and bus radial（TBR） tire was studied.The results showed that the low rolling resistance index of TBR tire had no correlation with the hardness index，tensile strength index and elongation at break index，it was suspected related to the rebound value index，it had a strong correlation with modulus at 300% elongation index.It was suspected to be related to lowloss factor（ tanδ）（20 and 100 ℃） index，and had a good correlation with low tanδ（60 ℃） index.It had no correlation with elasticity modulus index and low viscous modulus index.The tanδ（60 ℃） of tread compound could be used as a substitute for tire rolling resistance performance，low tanδ（60 ℃） index correction factor was 1/5，that was，tanδ（60 ℃） decreased for 0.1，the tire rolling resistance decreased by 16.4%. |
