电测量仪表可动系统固有频率的计算

The Caculation of Inherent Frequency of Electrical Instrumentation's Movable System

研究了张丝支承可动部分固有频率和局部频率的频谱与可动部分结构特性的关系。确定了在谱内固有频率的位置和分隔由可动部分和固定元件的几何形状以及纵向偏心率的大小来决定。提出了用电子数字计算机计算固有频率的程序方框图以及求螺旋形力矩游丝的固有频率的计算公式。

Researching the relationship between the frequent chart of the movable part's inherent frequency and part frequency of the tensile silk support and the movable part' s structure characteristic. Defining the inherent frequency' s position and partition in chart decided by the geometric figure of the movable part and the fixed cell, and the longitudinal eccentric rate' s size. Putting forward the computer program table of the inherent frequency and the caculating formula of the inherent frequency of the spiral moment hairspring.
