AI Technical Summary
Traditional cable anchors lack real-time axial force monitoring capabilities, resulting in long detection cycles, low efficiency, and an inability to promptly detect early failure warnings, posing structural safety risks.
By employing a flanged piezoelectric ceramic sensor based on the principle of acoustoelasticity, the sensor transmits and receives ultrasonic waves, records the time difference of flight, and calculates the axial force using calibration coefficients, thereby achieving real-time axial force monitoring and providing timely data support.
It enables real-time status assessment of cable-stayed structures, timely detection of axial force anomalies, prevention of safety accidents, and improvement of structural safety and durability.
