Optimization design for beam structures of rail weld CNC fine milling machine based on Ansys Workbench

摘要

If finite element models for beam structures of the rail weld CNC fine milling machine are built, and static analysis and modal analysis are used to model the beam structure, it can be concluded that the beam has sufficient margin in strength but lower stiffness. The beam structure is optimally designed with orthogonal test. After optimization, the beam body has been obviously improved in stiffness, and reduced lightly in weight.
