摘　　要：飞锯机由随动系统和锯切系统组成,其随动系统直接影响到锯切焊管的定尺精度。本文对随动控制系统进行了运动分析,并给出了运动方程,在此运动方程下随动系统既无刚性冲击又无柔性冲击,飞锯机在不增加伺服电机驱动力矩的情况下,快速返回,提高了定尺精度。The flying - saw consists of two parts ： the following system and the sawing system, of which the cut - to - length accuracy of sawing welded pipe is directly affected by the following system. A kinematical analysis of the following system is made and the equations for kinematical motion are given in the paper. With the equations in practice, there will be neither rigid shock nor soft shock in the following system. Therefore, the flying - saw device could come back faster without increasing the driving torque of the servo motor, resulting in increasing the sawing dimensional accuracy.
