Finite element analysis of motion pair of ball screw based on ABAQUS

Abstract

With the development of science and technology, the application field of ball screw is more and more extensive, in order to achieve higher precision, efficiency of transmission, and better sensitivity and synchronization, the ball screw must be studied more deeply, this paper will be through finite element analysis, research and analysis of various data under the force state of the ball screw. Specifically, this paper models the 3D model of the ball screw by modeling the professional modeling software SolidWorks, followed by finite element analysis on the Abaqus CAE software. The ball screw model includes balls, screws, nuts, and washers. The Abaqus software is used to analyze the force situation between the balls, nut raceways, and nut raceways when the ball screw is affected by axial force. After simulation analysis, the data that can be used for reference are obtained, which provides technical support for the design and optimization of ball screws.
