The Research And Optimization Of Lifting Platform Machine-Liquid Properties Of Copper Packaging Line

"JNMC copper cathode plate automatic packing production line" is developed by Lanzhou University of Technology with JNMC. Currently, the system has been successfully run in JNMC. But the hydraulic lifting platform of copper cathode plate automatic packing production line suffers from many problems mainly including great deformation of components, serious fuselage vibration, high pressure level of hydraulic system. Address these shortcomings, static and dynamic analysis of the hydraulic scissor lift platform-hydraulic combination and the hydraulic jar's position parameters optimization is carried out in this paper. The main work of this thesis are as follows:First, ANSYS finite-element software is used to static and dynamic analysis of the hydraulic lifting platform, the variation of the volume of hydraulic oil and the effective volume of hydraulic cylinders is calculated, the equivalent stiffness of Hydraulic lift platform is obtained.Secondly,ANSYS finite-element software is used to build the finite element model of the scissors hydraulic lift platform mechanical-hydraulic integrated system, followed by the system's static analysis.By static analysis, the deformation cloud of deformation of the each component of lifting platform under certain loads is obtained.Thirdly,the dynamic analysis of the finite element model is done,by modal analysis and harmonic response analysis, the first ten rank of inherent frequency,main vibration mode diagram and harmonic response characteristic curve is developed. By transient dynamic analysis, curves of displacement,velocity,acceleration under impact loads are carried out.Finally,the hydraulic system's working pressure of the hydraulic system has significant influence on its performance. The pressure value depends on the maximum push pressure of the piston during the lifting. C language is used to build optimization program, and the position parameters of the hydraulic jar is optimized. After the optimization, the working pressure of the lifting platform hydraulic system is reduced by 25.23%, and the pressure level is more stable, which indicates the certain extend of reduction of vibration during the lifting.Through this work, some theoretical reference will Provide for the design and development of Similar equipment in the future.
