| Abstract: | A three-dimensional model of machine tool bed was established with CAD software. After confirming boundary conditions, the thermal characters and deflections of machine tool bed were calculated with finite element analysis software. The influence of the parameters such as thermal source, restrictions, gravity etc. on the machine tool bed and parts of it was analyzed and compared. According to the analysis result, some restrictions were changed to optimize the thermal characters of machine tool bed. |
