Bionic Design for Column of Gantry Machining Center Using Honeycomb Structures

With the aim to improve the machining precision of a gantry machining center, bionic optimization design for ribs structure of its column was investigated. Firstly, based on the analysis of honeycomb structures, three kinds of bionic columns were discussed and simulated by finite element analysis method. The column structure with the best comprehensive performance was achieved according to the column design optimization system using the Gray Analytic Hierarchy Process. The bionics principles for ribs of column were concluded, which provided a new method for improving the traditional design and achieving comprehensive performance optimization structures of machine tool components.
