一、牵引力的测量 由于电测法的灵敏度高,在测力时就可利用机器上的零件做弹性元件,在其上粘贴电阻应变片即可进行测量。但有时这样做电阻应变片的输出太小,为了增加变形量以适应测量仪器的灵敏度,往往设计专用的弹性元件。测量 First, the traction force measurement Because of the high sensitivity of the electrical measurement method, when the force is measured, the parts on the machine can be used as the elastic element, and the resistance strain gauge can be attached to the measurement to perform the measurement. However, sometimes the output of the resistance strain gauge is too small. In order to increase the deformation amount to adapt to the sensitivity of the measurement instrument, a dedicated elastic element is often designed. measuring
