在设计测力计时,需对其一次元件一弹性测力环进行变形(直径的增减)计算,以便为选择传感器(电测法)或杠杆放大机构(机械测法)提供设计条件。文献[1]—[3]给出了圆形测力环(图1)当其矩形断面尺寸r/h<10的情况下的变形计算公式。其中r为环
In the design of the dynamometer, it is necessary to deform (increase or decrease of diameter) of the elastic force ring of its primary component in order to provide the design conditions for the selection of sensors (electric measurement method) or the lever amplification mechanism (mechanical measurement). The literature [1] - [3] gives the deformation calculation formula of the circular force ring (Figure 1) with the rectangular section size of r / h <10. Where r is a ring
