Research On Compressive Force Modeling And Performance Simulation For Cone Crusher

With the development of road, bridge, construction and other industries, gravel materials have been more and more widely used. The compressive crushing equipment is most widely used in bulk material breakage. With respect to the cone crusher, how to improve productivity, reduce energy consumption and improve life are the focus of concern. And, compressive force of crusher has influence on equipment working performance. So the research of compressive force has outstanding significance to dynamic performance analysis of the machine and wears and life prediction of broken parts.The papers analyzes the existing method of compressive force calculation and its deficiency, and builds a solution model of compressive force based on the material compression experiments and the experimental data analysis. It provides the basis of precise compressive force action for dynamic performance analysis of the complete machine and cavity optimization design.First of all, based on the laminated broken working theory of cone crusher, this paper analyzes bulk material movement in crushing cavity and cavity layering situation and discusses the key influencing factors of compressive force. With mechanics experimental study of compression processes of three kinds of rock materials using RMT-150B Rock mechanics test system, it gives a regression analysis on experimental data, builds three factors mathematical model of compressive force, and solves compressive loads distribution in details based on material layering situation. Secondly, based on the command language of Solver of Adams, it builds parameterized virtual prototyping model of cone crusher. With compressive force being input of the simulation model, it solves the results of cone crusher kinematics and dynamics at different kinds of materials, and obtains information of cone rotation speed and friction pair loads, etc. It hopes to determine the most optimal structure parameters and working parameters at design stage.Thirdly, based on ANSYS APDL language, established the crusher key components'parameterized finite element analysis model. With the application of virtual prototype simulation analysis results, get the stress results of danger node. Based on the cumulative fatigue damage theory, realized fatigue life estimation of key components, provided basis for parts design and optimization.Finally, based on the mentioned model, combining the integrated demand of heavy crushing equipment design and development, develop the Integrated Platform of Optimization Design and Performance Simulation for Cone Crusher, IPOSCC. Set domestic multi-cylinder hydraulic cone crusher PYGB1121 as application object, do the application verification for the function of software.
