Three Dimensional Fluid Simulation and Experimental Verification of Hydrostatic Guideway for Large Rotary Worktable

摘要

Relying on the major national science and technology special project, this study used the table 12 fan-shaped oil cavity hydrostatic guideway of CKS5235 CNC vertical lathe worktable, applied FLUENT processing software GAMBIT modeling and mesh generation the flow static pressure guide film, setting boundary conditions. Used simulation software FLUENT numerical analysis the dynamic process of hydrostatic slideway oil film flow field with temperature field and the basic bearing capacity, the effectiveness of three dimensional fluid simulation method for hydrostatic guideway in engineering design is verified by experiments. According to the results of three-dimensional fluid simulation, the hydrostatic guide structure of CKS5235 CNC vertical lathe worktable has been improved, achieve the speed performance improvement of the table, complete the major special technical research and acceptance.
