Abstract：Aiming at the problem of torque measurement with the cylinder type elastic element,the analysis was carried out with the material mechanics theory,and the position of maximum strain value on the surface of standard hollow cylinder under the action of torque was calculated.In addition,the standard hollow cylinder was simulated with ANSYS,a method of extracting the strain values of nodes in arbitrary direction in the model was proposed,and the simulation accuracy was verified.The cylinder type force sensor was simulated,and the optimal position for sticking strain gauge was extracted in combination with the theoretical analysis.A measurement circuit,which could help the proposed sensor eliminate the effect of tension and bending moment during the dynamic measurement,was designed.Therefore,the accurate measurement of torque can be realized,and the precision of cylinder type force sensor can be improved.The proposed method can play a guiding role in the related operation of complex structures.
