High stiffness of machine tool structure helps to improve the machining accuracy and the dynamic performance of machine tools. Based on the bionic structure, the theory of topology is used to optimize the stiffened plate structure design of the nasal type gear mil ing machine tool column which is made play the role of the skeleton. Through the static modal and finite element analysis of the prototypes and bionic column, it is found that the mass of the column is reduced and the quality of the specific stiffness structural efficiency and its static-dynamic performance are improved greatly.
