| 中文摘要: |
| 研究温度和拉伸速率对胎面材料拉伸力学性能的影响。结果表明：胎面材料的拉伸力学性能对拉伸速率具有一定的敏感性；在0～90 ℃温度范围内及大应变时，胎面材料的拉伸模量随温度升高而减小；在－30 ℃时，应力-应变曲线表现出“玻璃态”的特性，拉伸模量明显提高。Mooney-Rivlin模型模拟结果与试验结果相一致. |
| 英文摘要: |
| The influence of temperature and stretching rate on the mechanical properties of tread materials were investigated.The results showed that，the tensile mechanical properties of tread materials had a certain sensitivity to the stretching rates.The tensile modulus of tread materials decreased with the increase of temperature in the temperature range of 0～90 ℃ under the large strain scope；and the stress-strain curve showed the characteristics of glassy state and the tensile modulus significantly increased at the temperature of －30 ℃.The simulation results of Mooney-Rivlin constitutive model were consistent with the experimental results. |
