Dynamic Model And Simulation Study Of210t Converter Tilting Mechanism

Oxygen top-blown converter steelmaking is modern metallurgical enterprisesapplication of the main steel-making method, and its work is directly related to thesmooth production line. Oxygen top-blown converter equipment including furnace,tilting body, trunnion ring, trunnion shaft. The converter tilting institutions as the mainequipment in the converter steelmaking process to complete a smooth start andaccurate positioning of the furnace, in order to achieve a process operations of theconverter against the hot metal, steel, feeding, repair furnace. Steelmaking process,low-speed, overloading and poor working conditions, coupled with the frequent startand braking, especially motor startup in different ways that the effect of the converterdynamic behavior.In this paper introduce the structure, design principles, the basic designparameters, several of the structures and configurations, and the form of drive andtransmission of tilting mechanism.geometric modeling, numerical calculation andcomputer analysis methods, combined with the actual working conditions of theconverter,to establish the dynamic model for multi-point meshing flexible drivesystem of the210tons Full Suspension converter. First established a twelve massdynamic model of converter tilting system,which continues to simplified tothree-mass system dynamic model. Using the Lagrange equation establishmentmovement differential equations to solve to get the system natural frequency, criticalspeed. Provide assistance for the proper use of maintenance equipment, analyze andsolve equipment failures.Target210tons converter use virtual prototyping technology conduct virtualprototype motion simulation study. Fully understand the characteristics of the existinggood and general-purpose modeling software Solidworks application solidworkssoftware for geometric modeling and assembly of the tilting device. The Solidworksestablished a solid model imported into the kinematics and dynamic simulationsoftware ADAMS platform. Reference to geometrical parameters, physicalcharacteristics and constraints of the converter, establish the simulation model of FullSuspension converter, and simulation study under the role of gravity.Carried out atheoretical simulation of the converter torsion shaft and the trunnion when the motorcomplete to different startup and brake. The use of virtual simulation software cancomplete the simulation of physical prototype can not be completed numeroustimes,target subsequent design, equipment maintenance etc. all have practicalsignificance and engineering value in use.
