Modeling and Vibration Characteristics of Ground Mounted Friction Hoist

doi:10.3901/JME.2019.12.205

Abstract

Abstract: Ground mounted friction mine hoist is prone to vibration during operation, which plays a negative impact on its safety. A more accurate simulation model is established to investigate the vibration characteristics during braking period. The results indicate that longitudinal vibration is the main vibration mode whether it is normal braking or constant-deceleration emergency braking. For the former, the system only shows significant longitudinal vibration at the end of the braking, the vibration curve has a damping attenuation oscillation with 0 m/s2 as the equilibrium point, and the frequency is only a few hertz. For the constant-deceleration emergency braking condition, the vibration curve without rope slip exhibits a damping attenuation oscillation with a given deceleration value as the equilibrium point during the braking process; at the end of the emergency braking, the system will first produce a significant peak, and then exhibit similar vibration characteristics to that of the normal braking. Otherwise, the longitudinal vibration characteristics will be significantly different from that without rope slip. The proposed modeling methodology can be extended to the simulation modeling of other wire rope hoisting system, such as elevator. The vibration characteristics of the friction hoist during the braking process can provide judgment basis for monitoring its operating status.
