FEM-Based Topological Optimization on the Spindle Box of Heavy Duty CNC Lathe Machine

Abstract:

A topological optimization on the spindle box of a heavy duty lathe was studied. The objective of the work was to seek optimum material distribution and lighter mass of the spindle box, while maintain its original stiffness, strength and natural frequencies. Firstly, static and modal analyses were carried out. Then, the topological optimization was conducted through constraints of spindle hole’s displacement and lower-order natural frequencies, with minimized material volume as objective. Finally, a spindle box with optimized structure was obtained.
