Abstract: Based on the finite element method, taking Computer numerical control (CNC) machine tool spindle as the research object, using the finite element analysis soft ware ANSYS work bench, the result of the modal analysis is used to take structural dynamic optimization. Firstly, ANSYS Work bench is used to spindle modal calculation, analysis the natural frequencies and modal shapes, further, weak points on the machine structure are analyzed and optimization methods are pointed out. Finally, in order to optimize the weak points of the object, considering the increment of natural frequency of the spindle as the optimization objective, the structural dynamic modification optimizes is taken.

Keywords: ANSYS, modal analysis, dynamic optimization, structural modification
