提出了一个考虑模态噪声影响的基于残余力向量法的损伤识别两步法。
A new two-step damage identification method based on residual force vector considering the impact of measurement error (noise) in most cases is proposed.
通常，人们关心系统的弹性体模态，因为主要是由那些模态导致了我们遇到的所有噪声和振动问题。
Typically, people are concerned about the flexible modes of the system because those are the modes that generally cause all the noise and vibration problems that we encounter.
从理论和试验两个方面分析和研究噪声对识别精度的影响，影响识别精度的因素，以及部分模态成分的模态参数不能够被识别的原因。
The influence of noise on identification precision, the effect factor of the computing precision and the reason of missing estimation some modes were analyzed and discussed.
