摘要： 基于LMS Test. lab声振试验系统对Z4113型钻床进行动态特性试验分析，并利用系统分析中的Nyquist稳定性判据，准确识别结构的薄弱环节，最终对钻床工作台进行动力修改预测。

关键词: 振动与波, 钻床, 稳定性判据, 薄弱环节, 修改预测

Abstract: The dynamic characteristic testing for Z4113 bench drilling machine was carried out with the LMS Test.lab acoustic vibration testing system. The structural weakening of the machine was recognized by using the Nyquist stability criterion in system analysis. Finally the dynamic modification of the machine was discussed.

Key words: vibration and wave, bench drilling machine, stability criterion, weak points, modification prediction
