| 中文摘要: |
| 本文提出一种新的模态分析方法—用声信号识别构件模态频率.传声器不与结构表面接触,消除了附加质量的影响.同时,结合时间序列谱分析法改善并提高了响应谱的精度. |
| 英文摘要: |
| This paper presents a new method of modal analysis, that is, a modal frequency identification technique for a structure by radiated sound measuring. As the microphone does not get in touch with the measured body, it eliminates the effect of additional mas |
