Simulation Analysis of Dynamic Characteristics of Hoist System
In order to further solve the problems of reliability and safety of the hoisting system in emergency braking and reduce the impact on the system,taking the permanent magnet internally mounted mine hoist as an example,the simulation model of the hydraulic braking system was constructed based on Simulation X software on the basis of the analysis of its basic structure,and the accuracy of the model was verified through the on-site test.Finally,the influence of different braking deceleration speeds on the electromagnetic torque,braking torque and wire rope tension in the emergency braking process of the hoist is simulated and analysed,so as to lay a theoretical foundation for the formulation of reasonable emergency braking strategies in practical production.
