Abstract

The column of the horizontal machining centre has been studied. In order to achieve the deformation cloud diagram under static loads and natural frequencies, the finite element model is established. Then structural topology optimization based on variable density method is conducted. The irregular spatial structure obtained by topology optimization is simplified and abstracted. And then the structure is redesigned with the consideration of manufacturability. The optimized structure is more reasonable. It provides a theoretical basis for the improvement of column structure.
