轴系固有扭频调整用线性估算法

A Linear Method for Adjusting Natural Torsional Vibration Frequencies of Shafts

通过一阶灵敏度分析，就借助于改变轴系参数来调整轴系固有扭振频率问题进行详细讨论。提出一阶估算法，并给出具体算例。利用该法可方便地确定待改变参数之最佳轴段的具体位置及其参数变化量。

In this paper, the problem about adjusting natural torsional vibration frequencies of shaft by varying its parameters is discussed in detail,a linear method is proposed and some examples about it are presented also. With the method put forth in this paper,the location of optimum shaft can be determined conveniontly.
