Experimental study on longitudinal vibration of mine hosting rope subjected to disturbance excitations by ADAMS

The periodic and impact excitations caused by drum winding and interface misalignment of steel guides always result in hoisting instability in mine shafts. This paper focuses on investigating the longitudinal response of the lifting system subjected to the two disturbance excitations. First, the periodic velocity and acceleration excitation from an experimental model was derived. Second, the virtual prototype model for the longitudinal vibration of the hoisting rope subjected to the two excitations was built in ADAMS, and the validity of the established virtual prototype model was verified experimentally. Eventually, the acceleration of the conveyance under the disturbance excitations were effectively reduced by applying a vibration reduction device, and the virtual simulation results confirmed the effectiveness of the proposed device. This paper can provide a good scheme for the research of vibration reduction in mine hoisting systems.
