The Topological Optimization Design of Cross Beams Structure of Shaped Stone Turning-Milling CNC (HTM50200)

Abstract:

To reduce the overall mass of the machine tools, this paper made the structural lightweight design to crossbeams of the HTM series gantry machine by topology optimization. The topology optimization mathematical model was built by taking the quality as the constraint, overall stiffness to the maximum (complicance to the minimum) as the design goals. It also took HTM50200 Turning Milling Center as an example, put forward an asymmetric layout structure of auxiliary hole according to the optimization results by numerical simulation and calculation of ANSYS. By verified, the mass of the structure was 2.76% lower than traditional structure, and the maximum deformation decreased by 16.07%. By applying the topology optimization method to the design process of the HTM series machining center, the utilization of materials will be improved and the production costs will be reduced.
