Modeling and Simulation of Mine Hoist Hydraulic Braking System

In order to verify the accurate design of the mine hoist hydraulic braking system, the mathematical model of a hydraulic braking system is established. Its simulation model is built by the AMEsim software. The oil pressure contacting break is simulated to verify. The oil pressure, disc spring deformation, disc spring force and the positive braking pressure are analyzed during the normal driving and normal parking of the mine hoist. The oil pressure are also analyzed during the primary braking and secondary braking of the mine hoist. The simulation results are in line with the theoretical results and actual operating rules. Simulation and theory are combined to study the working principle of mine hoist the hydraulic hoist system. It can deepen the understanding of miners on the system with a guiding significance. The modeling and simulation method can provide some reference for the verification of the accuracy of the design system. The design development cycle of the system is shortened and its reliability is improved.
