摘要
In order to meet the testing accuracy of torque in the test of biological bone tissue torsion behavior, a strain gauge torque sensor based on multi-beam structure is designed. The mechanical model of the torque sensor is given and the parameters of the elastic beam structure have been optimized by finite element analysis. Finally the material of the structure and processing technology are determined and static calibration is carried out. Experimental results show that the linearity is 0.9% and the sensitivity is 0.14mV/V in the measurement range from 0 to 0.5N center dot m with 0.3% resolution.
