倍捻锭子的动力特性分析——模态综合法的应用

Vibration Analysis of Double Twisting Spindle through Synthesis of Component Modes

首先根据倍捻锭子的实际结构建立起计算模型,并详细介绍模态综合法对倍捻锭子的计算过程;另外传递矩阵法作为处理回转轴系的传统方法,这里只作简单介绍;最后运用模态测试技术对理论计算进行了校核.结果表明,理论计算和模态测试值基本吻合,这为今后对倍捻锭子的进一步研究提供依据.

First, the calculating model of double twisting spindle is set up. Then, dynamic analysis of the spindle through synthesis of component modes is introduced in detail. And the method of transfer matrix, as a traditional one dealing with spindle only is introduced simply. Last, the modal testing on the spindle is made, whose purpose is to verify the results from the synthesis of component modes and those from the method transfer matrix.
