| 中文摘要: |
| 采用压缩屈挠试验方法，研究氯丁橡胶（CR）、三元乙丙橡胶（EPDM）和硅橡胶（MVQ）的压缩疲劳性能。结果表明：在相同的试验条件下，CR的疲劳寿命最长，EPDM次之，MVQ最短；3种胶料的静、动压缩变形率与永久变形的一致性较好，且永久变形越大，胶料的温升越高。 |
| 英文摘要: |
| The compression dynamic properties of CR，EPDM and MVQ were tested using controlled stress dynamic mechanical tester (flexometer).The experimental testing results showed that CR possessed the best fatigue life and MVQ showed the worst.For all three kinds of rubber，the permanent set showed good correlation with the static and dynamic compression ratios.Moreover，when the permanent set was higher，the heat build-up was higher. |
