Abstract：

The three-dimensional geometric model of large machine bed was established by Pro/Engineer, and then the finite element analysis of thermal deformation was carried out by Pro/Engineer module. Therefore, both the distribution of temperature field for the machine bed under the thermal equilibrium state and the amount of thermal deformation for the machine bed along the Y and Z directions were obtained. The internal structure of the machine bed was optimized and an external cooling device was added based on the analysis result. Furthermore, a finite element analysis of thermal deformation was performed again, and the effect was verified once again. Based on the research above, the machine bed temperature rise and thermal deformation experiments were carried out. The results show that the values of finite element analysis and the detection are in good consistency, and the heat deformation of the machine bed designed by optimization is significantly reduced. With the improved working efficiency and the reduced production cost, the accuracy of machine is further improved.
