摘　　要：以螺旋槽专用数控机床使用的盘铣刀为研究对象,分析螺旋曲面铣削系统的动态特性。首先建立盘铣刀及主轴的三维模型,通过有限元仿真软件对盘铣刀在装配状态下进行模态分析,进而计算出盘铣刀装配状态下的固有频率和对应的模态振型;之后通过谐响应分析得出盘铣刀在装配状态下容易发生共振的频率主要集中的位置。此研究结果对盘铣刀振动特性的分析具有重要的指导意义。In this paper,the dynamic characteristics of the spiral surface milling system are analyzed based on the disk milling cutter used in the special CNC machine tool for spiral groove.Firstly,the three-dimensional model of the disc milling cutter and the spindle is established,and the modal analysis of the disc milling cutter in the assembly state are carried out by the finite element simulation software.Then the natural frequency and corresponding modal vibration mode of the disc milling cutter in the assembly state are calculated;aftefwards,the main resonance frequency concentration position of the disc milling cutter in the assembly state is obtained by the harmonic response analysis.This research result has important guiding significance for the analysis of the vibration characteristics of disc milling cutters.
