Design Optimization And Performance Analysis Of BFPC CNC Lathe Bed

With the increasing of modern science and technology,the mechanical manufacturing towards high precision,high automation and high efficiency development direction.,it asks for higher requirements of the static and dynamic performance of the bed,studying to adopt the new material manufacturing machine tool lathe bed become a hot problem in the mechanical manufacturing industry.This paper is based on TCK4558/960 CNC lathe bed,he design,optimization and dynamic performance of the basalt fiber resin concrete(BFPC)CNC lathe bed were studied,the main content is as follows:(1)Labor the various components and the static stress distribution of the TCK4558/960 slant bed horizontal CNC lathe bed under typical working conditions,mainly to solve simplified the force and forces of exerting,and the guide of pressure everywhere has carried on the detailed calculation.(2)On the basis of the prototype lathe bed,In ensuring its main contour structure size,and other components(spindle box,slide the saddle and tailstock,etc.)contact structure size remains the same,the preliminary design BFPC lathe bed.(3)Through the method of finite element simulation analysis,analyzed the total deformation of clouds、each of the various deformation clouds、equivalent stress cloud and equivalent strain cloud of two kinds of materials bed under typical conditions,compare the results of analysis,preliminary evidence that BFPC lathe bed feasibility to improve the static performance of the machine tool.(4)Through the method of finite element simulation analysis,the natural frequencies and modes of the first six modes of two kinds of material bed body were analyzed,he harmonic response analysis of two kinds of material bed body which under the same period of load is carried out,the results are compared and analyzed,preliminary evidence that BFPC lathe bed feasibility to improve the dynamic performance of the machine tool.(5)To further improve the static,dynamic performance and light quality of BFPC lathe bed,with the multi-objective topology optimization design theory,using the HyperMesh processor and the OptiStruct solver to design multi-objective topology optimization for BFPC lathe bed.(6)Analyzed the static and dynamic performance of optimal structure BFPC bed body,compared and analyzed the corresponding performance of optimize the front and rear BFPC lathe bed and prototype lathe bed,The effectiveness of multi-objective topological optimal design of further improve the static,dynamic performance and light quality of BFPC lathe bed is proved.
