Dynamic Characteristics Analysis of Ball Screw Based on Workbench
Pin Hong, Ying Pan, Ting Zhang

Abstract
The ball screw is widely used in CNC machine tools with high precision, high efficiency, high sensitivity and other advantages. However, the ball screw has the shortcomings of low stiffness. This paper researched the single ball screw, built the ball screw model with three-dimensional modeling software Solidworks, and did the statics analysis, modal analysis and harmonic response analysis respectively using the model which was imported into finite element analysis software ANSYS Workbench, got the natural frequencies and the corresponding vibration type and the response characteristics under the rated load, which provides a basis for the transmission accuracy and structural design of ball screw.
