Finite Element Analysis And Optimization Design Of TX1600Boring-milling Machining Center

With the rapid development of CNC machine tools, functional composite becomesa major development direction of machine tools while boring-milling machining centeris one hotspot of the current researches at home and abroad. With its advanced R&Dmodel, low-cost and short-period R&D efficiency and a powerful advantage of paralleldesign and manufacturing,virtual prototyping technology (VPT) has been widely usedin mechanical industry during the design process of machine tools.In this paper, simulation researches were carried out on TX1600boring-millingmachining center from various views with the use of VPT, the results of which wouldhave a guiding role on the engineering practice. The key points of this article read asfollows:On the basis of the materials at home and overseas，the concept origin anddeveloping tendency of machining center is studied.Both the development andapplication of the foreign machining center and current condition,and developingtendency of ours ale studied． Additionally,the keytechnological problems whichinfluence the development of machining center，and the problems which need to besolved urgently so that the machining center can develop quickly are studied．The virtual prototype of TX1600boring-milling machining center was built inSolidWorks with feature-based modeling techniques and top-down design theory, whichbecame the basis of kinematics simulation analysis and optimal designOn TX1600boring-milling machining center column vertical structure based onsolidmodeling and finite element analysis was carried out by static analysis has beenthe displacement column structure and stress cloud,and the stress and strain of theoverall structure under the cutting force and gravity were researched.Modal analysis were carried out on the components and the whole body of themilling part of the machining center in the ANSYS based on modal theory and six orders natural vibration characteristics were obtained.Use the harmonic analysis get thestructure to harmonic displacement.In order to reduce structure mass and improve thenatural frequencies, the optimal design of the beam was carried out based onoptimization design theory.In order to reduce structure mass and improve the natural frequencies, the optimaldesign of the beam was carried out based on optimization design theory.
