| 摘要: |
| 瞬态激励试验是获得机械系统动态参数的重要方法之一。本文应用瞬态激振法对 S1-235超高精度车床的主轴系统进行了动态试验，介绍了瞬态激励法的试验技术、基本原理和信号处理特点，测定了系统的固有频率、阻尼系数和动刚度。并通过 Levy 曲线拟合方法获得了系统的传递函数。 |

| Abstract: |
| The transient exciting test is one of the important methods to get the dynamic parameters of mechanical systems. Adopting the transient exciting methods，the dynamic exciting test has been carvied out for the main spindle system of machine tool Sl-235 with super-accuracy in this paper.
The test technique the foundamental principle and the characteristic of signal processing of the transient exciting methods are presented here Final1y the natural friqnences，the damping ratio and the dynamic stiffness have been determined. The transfer function of system has been obtained by Levy's direct curve fitting methods. |
