Structural Design and Vibration Analysis of the Built-in Damping Boring Bar

Abstract

A series of related researches have been carried out in the process of deep hole machining with boring burrs, where the long diameter of the boring bar is relatively prone to chatter. Firstly, the structural design and detailed design of the damping boring bar was completed, a three-dimensional model was established, a dynamic equation was established for the damping system and using ANSYS for modal analysis and harmonic response analysis. Finally, the comparison between the solid boring bar and the analysis results of the damping boring bar is compared and the conclusion that the new type damping boring bar has good damping performance is obtained.
