Finite element analysis of the spindle ram-slider assembly body on the domestic large gantry machine tool

摘要

Machine working environment was simulated by using ANSYS software for analysis and calculation. Modal analysis results indicated that machine tools didn't produce resonance during the machine working. Harmonic response analysis result shrew the displacement response frequency was 42Hz along the Y, Z two directions on the bottom of ram, and X direction's response frequency was 43 Hz. The conclusion given by this paper has guiding significance to use the machine safely in the future.
