Structural Design and Mechanical Simulation of PS-90-Y Hydraulic Disc Brake Device

Abstract

 To improve the safety and reliability of mining operations for medium depth mine hoists, this paper designs a PS-90-Y hydraulic disc brake device and conducts in-depth research on its structure, and mechanical properties. Firstly, the basic structural composition and key parameters of the hydraulic disc brake system were elaborated, including core components such as working calipers, safety calipers, and hydraulic thrust cylinders. Based on the theory of braking dynamics, a mathematical model of the hydraulic disc brake system was established. The key parameters of the brake system, such as braking torque, positive pressure, and friction coefficient, were determined through theoretical calculations to ensure that the braking performance meets the high load requirements of the mine hoist. In terms of structural design, the overall optimization of the thrust hydraulic cylinder was emphasized to improve its load-bearing capacity and response speed. At the same time, mechanical simulations were conducted on key components such as working calipers, lever mechanisms, and brake discs to verify their structural strength, stiffness, and fatigue life under extreme working conditions, ensuring the reliability of system operation. The experimental and simulation results show that the designed PS-90-Y hydraulic disc brake device can achieve a maximum positive pressure of 90 KN on one side, fully meeting the high safety braking requirements of deep well drilling and mine hoisting. This study provides theoretical basis and engineering reference for the optimization design of the braking system of mine hoists, which is of great significance for improving the safety of mining operations.
