| 中文摘要: |
| 开发1×1钢丝帘线，并研究其性能。结果表明：采用校直器校直和加捻反扭两种工艺均可以得到符合设计要求的1×1钢丝帘线，校直器校直的钢丝帘线残余扭转更稳定，而加捻反扭的钢丝帘线直线性更好；在材料确定的情况下，1×1钢丝帘线的弯曲刚度和低负荷伸长率主要与直径相关，而与强度关系不大；在1 500 MPa试验压力下，1×0.30ST钢丝帘线的亨特疲劳性能比2×0.30ST钢丝帘线更好。 |
| 英文摘要: |
| 1×1 steel cord was developped and its performance was researched.The results showed that both straightening with a straightener and twisting and revers-twisting processes could achieve 1×1 steel cord that met the design requirements，and the residual torsion of the steel cord straightened by the straightener was more stable，while the straightness of the steel cord twisted and revers-twisted was better.With the material determined，the bending stiffness and low load elongation of 1×1 steel cord were mainly related to diameter，but less relation to strength.At 1500 MPa test pressure，Hunter fatigue performance of 1×0.30ST steel cord was better than that of 2 × 0.30ST steel cord. |
