| Abstract: | According to the characteristics of the A,C douhle-swivel head five-axis gantry type machining center, a coupled thermal-mechanical finite element equation was set up based on thermo-elasticity mechanism and finite theory in this paper. By applying the equation to the spindle system, based on the determining of internal heat seurce, transmission ways and boundary conditions, the temperature field distribution and the thermal deformation are attained. The result is evaluated, and the research provides technological support to design the A ,C double-swivel head spindle system. |
