| 中文摘要: |
| 研究动态疲劳对钢丝帘线／橡胶粘合性能的影响。结果表明：随着动态疲劳拉伸形变的增大，钢丝帘线／橡胶的粘合力逐渐减小，抽出钢丝表面附胶呈螺纹状，且螺纹越明显，粘合力越大；随着动态疲劳弯曲形变的增大，钢丝帘线／橡胶的粘合力小幅下降，抽出钢丝表面附胶分布不均，受拉面附胶少，受压面附胶多；随着停放时间的延长，钢丝帘线／橡胶的粘合力先增大后减小，当停放时间为32 h时粘合力最大。 |
| 英文摘要: |
| The effects of dynamic fatigue on the adhesion property between steel cords and rubber were investigated. The results showed that， as tensile deformation increased， the adhesion force of steel cords/rubber decreased gradually， and the covered rubber on the steel cord after pull-out appeared to form screw thread patterns. The adhesion force was higher when the screw thread pattern was more distinct. As the bending amplitude increased， the adhesion force of steel cords/rubber decreased slightly ， and the covered rubber on the steel cord after pull-out was not uniform ： less rubber on the stretched side and more rubber on the contracted side. As the parking time extended， the adhesion force increased at first and then decreased， and the maximum value appeared at 32 hours of parking time. |
