| 摘 要： | 本文提出了一种评估机床主轴的动刚性的一种新方法,此方法以机床主轴的固有频率为基础,在安装在机床主轴上的实验棒的半径方向上加振动脉冲,测出其固有频率,然后用固有频率算出主轴的刚度,另外对被测的机床又进行了主铣刀切削实验,得出了表面粗糙度与刚度的相关性.

| Abstract: | In order to estimate dynamic stiffness of a spindle on a machine, a new method is presented. The natural frequency of the bar is measured through exciting the straight bar fixed at the spindle of the machine in radial direction with an impulse hammer, based on the natural frequency of the machine spindle. The relatirity between the surface roughress of the workpiece and the siffness of the machine has been obtained, by means of calculating the stiffness of the fixed end of the bar and conducting end milling tests on the machines. |
