Mine Hoisting System Based On Virtual Prototype Technology Research

In order to explore the application of the virtual prototype technology in minehoisting system, taking the2JK-3/20type winding hoist as the prototype, this paperstudied the associated hoisting system and conducted a thorough and penetratinganalysis on its kinematics and dynamics simulation.The tasks achieved in the research are the followings:1) Based on the multibody mechanical system dynamics theory, the paperstudied and summaried the specific programs about kinematics and dynamicssimulation analysis for the mine hoisting system;2) Based on the the running theory of the mine hoisting system, the selectionand calculation of the related components for the hoisting system was completed,which laid a solid foundation for the establishment of the prototype model;3) The partial solid models of the cage hoisting system was created and theinitial assembly for the system was completed, meanwhile the parts of the systemmodel were successfully imported into ADAMS simulation platform by theseamless connection technology of graphics between ADAMS and Pro/E;4) The paper made a thorough research on the creation method ofsteel-wire-rope model in ADAMS environment and successfully createdcorresponding hoisting steel-wire-rope models;5) The reseach not only provided the virtual assembly between the hoistingsteel-wire-rope models and the partial solid models, but improved the virtualsettings of the prototype and constructed the virtual prototype model for the hoistingsystem;6) Through the kinematics and dynamics simulation analysis of the virtualprototype model, the research has not only gained some important kinematicscurves such as the main-shaft angular velocity and acceleration, the cage runningheight, velocity and acceleration, but obtained other valuable dynamics statistics likethe steel-wire-rope tension curve, the deformation curve, the drag-force curve of the hoisting system, the winding-force of the drum and the main-shaft powerconsumption curve.The simulation analysis indicates that the establishment of the virtual prototypemodel, the virtual-environment settings, and the relative kinematics and dynamicscurves are basically consistent with the actual situation.
