Experimental Study of the Dynamic Performance of a Cable with a Detecting Robot

Abstract

To analyze further the dynamic characteristics of the robotcable system, similar experimental models of cables on the Junshan Highway Bridge are constructed. To study the effect of high-altitude wind load on the safe performance of the cable and the robots climbing ability, transverse wind load is simulated and wind-load equivalent experiments on cable vibration are performed on the robot to simulate high-altitude conditions. Vibration amplitude and acceleration of the cable slightly increase under Grade 7 wind, which demonstrates the stability of the cablerobot system.
