Analysis Of Transverse Vibration Of Wire Rope In Flexible Hoisting System

Taking the flexible hoisting system as the research object, the transverse vibration mathematical model of the steel wire rope of the winding hoisting system is established, and the transverse vibration displacement, velocity and acceleration of the steel wire rope at 18 m away from one end of the wire rope under the sine excitation at other end is obtained through the comparison and verification of the results from the mathematical model, mechanical model and experiment. The results show that: for the length of the wire rope of 20 m, under the sine excitation at the end of amplitude of 0.002 m and frequency of 20 Hz, the transverse vibration displacement at 2 m from one end of the wire rope with length of 20 m is basically between -0.005 m and 0.005 m, the transverse vibration velocity at 2 m from one end of the wire rope is basically between -0.04 m/s and 0.04 m/s, and the transverse vibration acceleration of the wire rope is basically between -0.5 m/s(2) and 0.5 m/s(2). And the transverse vibration displacement decreases near the end, meanwhile the transverse vibration frequency increases with the reduction of length of vertical section of wire rope.
