“…Zhang et al [5] optimized the parameters of a guide shoe to suppress car vibration by studying the relationship between the deformation amount of the guide shoe and the restoring force. Han et al [6] studied the mechanical model of the elevator guiding system and obtained the relationship between the load and deformation of the guide shoe. In elevator hoisting systems, the investigation into vibration-damping mechanisms primarily centers on hydraulic floating sky wheels, electromagnetic active guide shoes, hydraulic active guide shoes, servomotor active guide shoes, and magnetic levitation guide shoes [7].…”

In the mine hoisting system, rigid guide failures and the influence of internal and external airflow intensify vessel transverse vibration, heightening demands on operational safety and equipment reliability. This paper focuses on integrating magnetorheological dampers and disc springs as the roller cage shoe buffer for vibration control, resulting in an innovative buffer device. The structure and magnetic circuit were meticulously designed. Using Maxwell simulation, we analyzed the impact of magnetic circuit parameters—specifically the damping gap and core radius—on the magnetorheological damper. We optimized these parameters through orthogonal testing to enhance damping and vibration reduction. This led to a notable 58% increase in the damper output force. A virtual prototype of the lifting system under actual working conditions was established. A simulation analysis verified the vibration-damping performance of the optimized roller cage shoe. The results indicate that the new roller cage shoes effectively inhibit transverse vibration, surpassing traditional roller cage shoe performance. This is scientifically and practically significant for ensuring safe cage shoe lifting system operation. This paper can provide a crucial theoretical basis for the design of roller cage shoes in ultra-deep mine lifting systems.
