摘要:
为研究悬索桥碳纤维增强复合材料(carbon fiber reinforced plastics,CFRP)主缆在索夹处的摩擦学性能,分析主缆与索夹间的摩擦接触特征,引用摩擦因数相关计算公式,分别进行平直接触及实桥接触下的当量摩擦因数试验.结果表明,CFRP主缆与索夹间的摩擦因数约为0.36,能满足抗滑移安全性能设计要求;径向挤压应力小于14.6 MPa时,CFRP丝与索夹的摩擦学性能比较稳定,径向挤压应力大于14.6 MPa时,摩擦因数有减小趋势;两种接触条件下,摩擦因数能较好吻合;理论计算偏于设计安全,适用于CFRP主缆与索夹间摩擦因数的计算.
Abstract:
In order to investigate the tribological properties between carbon fiber reinforced plastics(CFRP) main cable and clamp of suspension bridge, the contact characteristics of friction were analyzed theoretically. A formula for calculating the friction coefficient was introduced. The tests were conducted under flat contact condition and real bridge contact condition. Theoretical and experimental results show that, the friction coefficient between CFRP main cable and clamp is about 0.36.The tribological properties of CFRP cable can meet the design standards. The tribological properties between CFRP main cable and clamp are stable when radial compressive stress is less than 14.6 MPa, but the friction coefficient decrease when radial compressive stress is greater than 14.6 MPa. The friction coefficient under the two contact conditions can agree well. The theoretical design formula, which is safe for design, is suitable for calculating the friction coefficient between CFRP main cable and clamp.
