Research on Load Response of Ball Screw Pair Feed System
The ball screw pair mainly consists of screw,nut,ball,and circulation system.Its main function is to convert rota-tional motion into linear motion,such as the movement of the tool holder in a lathe.Currently,it is widely used in fields such as machine tools,aerospace,aviation,and nuclear industry.It is very meaningful to study the vibration response of the ball screw feed system under different impact conditions by establishing the dynamic equation.This article first establishes the dynamic equation of the feed system through the Lagrange second type equation,and then solves the equation using the finite element method to achieve simulation of the vibration response of the ball screw nut under different load impacts.
