Numerical Analysis of the Ultrasonic Honing Chatter Based on the Stribeck Model

Abstract

Chatter easily occurs in machining, which is influenced by many factors. The power ultrasonic vibration honing equipment is taken as the research object. The dynamic friction is studied and the dynamics model is established based on the Stribeck model. The describing function of the ultrasonic honing friction characteristics is calculated. The stability of ultrasonic honing nonlinear system is analyzed. The conditions are studied, on which chatter occurs. The expressions of chatter amplitude and frequency are given. The research provides the theoretical basis on which chatter can be effectively avoided when ultrasonic honing equipment is designed.
