Abstract

Abstract: Because the stressed structure of the boring bar in machine tool is a cantilever beam, and it is very easy to produce vibration. To study the vibration problem of boring bar, the general structure of boring bar was improved into the built-in damping core boring bar structure composed of two materials, according to the principle of self-excited vibration's coupling flutter and forced vibration's dynamic damping. At the same time, according to the principle that reasonable arrangement of small stiffness of the boring bar could reduce vibration, the composite structure boring bar was cut flat expecting to reach optimal damping effect. With the aid of finite element method software, three different types of boring bar models were established which were circular structure, cut flat structure and cut flat composite structure. In the same conditions, statics analysis and dynamic analysis of the three kinds of boring bar were done respectively. It shows that the structure of the composite material cutting flat boring bar has better damping effect by comparing the simulation results.
