模态置信标准（MAC）在环锭细纱机机架模态识别中的应用

The Application of MAC in Spinning Frames's Modal Identification

应用模态置信标准（ＭＡＣ）的概念对细纱机机架的模态进行了辨识。实验和分析计算表明，ＭＡＣ可以弥补常用模态识别方法的不足，使模态参数的评估定量化。

With MAC concept,the modal of spinning frames is identified. The experiments and analysis show that MAC can make the normal modal identifying methods more complete,and quantify the accessing of modal parameters.
