Dynamic analysis on a cable with a climbing robot

Abstract

Cable-climbing robot usually works in a high-altitude environment. The stability and safety are very important. To analyze further the dynamic performance of the robot-cable system, similar experimental models of cables are set up, and vibration experiments are conducted. To study the effects of high-altitude wind load on the safe performance of the cable and the robot, transverse wind load is simulated, and wind-load equivalent experiments on cable vibration is performed. Vibration amplitude and acceleration of the cable slightly increase under Grade 7 wind, which is significantly less than two points and five times the cable diameter. Thus, the stability of the cable system is in the acceptable scope.
