| 摘 要： | 对 钢丝帘线橡胶复合材料在拉伸循环载荷下的疲劳特性进行了试验研究,分析了最大应力、加载频率对材料疲劳寿命的影响以及疲劳过程中的滞后损失和温升,根据疲劳寿命图得到了线性寿命预报方程。研究表明,在载荷控制下该材料的疲劳过程呈现明显的三阶段规律,两步等幅加载实验证明这一规律同样适用于有损试件的疲劳过程。

| Abstract: | The fatigue properties of steel cord rubber composite under T T loading are studied in this paper. The effects of maximum stress and frequency on fatigue life are analyzed and the hysteretic loss and the variation of temperature during the cyclic tension are obtained as well. A linear life prediction equation is given in terms of the fatigue life diagram. The results indicate that the increase in the maximum strain exhibits a three stage tendency. The two step experiments demonstrate that this tendency also exists in the fatigue process of defected specimens. |
