Abstract

Cable tension is an important parameter for monitoring the health of cable-supported bridges. Live loads cause periodic changes in cable tension. Given the lack of test methods for cyclic cable tension, the resonance-enhanced magnetoelastic (REME) effect was adopted for cable tension monitoring. Combining the magnetoelastic effect and the electromagnetic induction theory, the relationship between cable tension and the REME sensor’s induced voltage was deduced. This relationship indicated the feasibility of using the REME effect to monitor cable tension. According to the variation law of cable tension, a cyclic cable tension monitoring experiment was carried out. Based on the experimental results, a cyclic cable tension monitoring method via the REME effect was proposed. When the tension variation amplitude was less than 100% of the design tension, the monitoring error was less than 5%. The proposed method could be used to accurately monitor the large-amplitude cyclic cable tension.

通过共振增强磁弹性效应监测大振幅循环电缆张力

摘要缆索张力是监测缆索支撑桥梁健康状况的一个重要参数。活载荷会导致拉索张力发生周期性变化。由于缺乏周期性缆索张力的测试方法，因此采用共振增强磁弹性（REME）效应来监测缆索张力。结合磁弹性效应和电磁感应理论，推导出了电缆张力与 REME 传感器感应电压之间的关系。这一关系表明利用 REME 效应监测电缆张力是可行的。根据电缆张力的变化规律，进行了周期性电缆张力监测实验。根据实验结果，提出了一种利用 REME 效应的周期性电缆张力监测方法。当张力变化幅度小于设计张力的 100%时，监测误差小于 5%。所提出的方法可用于精确监测大振幅周期性电缆张力。
