摘要

介绍了运用模态分析技术进行挠性转子动平衡参数识别的方法。不必加试重只需一次升速

将动不平衡量视作轴系的模态参数

根据转子的振动响应运用模态分析技术确定轴系的各阶模态不平衡量。对该方法进行的试验验证表明

运用模态分析技术进行挠性转子动平衡参数识别有效可行。

Abstract

The parameter identification method in flexible rotor dynamic balancing by using the model analysis technology has been presented.This method needs only run-up once instead adding the test mass

regarding the mass of dynamic unbalancing as the paramenters of rotor shafting system's modal parameter

and according to the vibration responds

the n-step modal unbalancing can be determined by using the model analysis technology.A vast amount of verification tests shows that this method is effective and feasible.
