| 中文摘要: |
| 研究了采用普通、半有效和有效硫化体系的NR/BR(共混比为70/30)硫化胶在同一表观交联密度下的疲劳寿命，比较了3种硫化体系硫化胶的疲劳特征参数β和C0值，并采用指数函数模型拟合出3种硫化体系硫化胶的疲劳寿命S-N曲线方程，其中最大相对偏差只有-6.52%，相关系数均大于0.953 5 ，可较好地描述不同硫化体系的NR/BR共混胶料的动态疲劳过程。 |
| 英文摘要: |
| The fatigue life of NR/BR(70/30) vulcanizates cured with conventional，semi-efficient or efficient curing systems and possessing the same apparent crosslinking density was investigated，the fatigue parameters β and C0 of the said 3 vulcanizates were compared to each other，and the curve equations for describing the fatigue life of the vulcanizates cured with 3 different curing systems were fitted to the exponential function model.The equations with the maximum relative error only up to -6.25% and the correlation factors greater than 0.953 5 were suitable to describe the dynamic fatigue process of NR/BR vulcanizates cured with different curing system. |
