The detection of dynamic torque plays a very important role in the operation of rotary power equipment.Through the real-time monitoring of the torque of the equipment,the working state of the equipment can be indirectly analyzed.In this paper,a non-contact dynamic torque sensor is designed,which can indirectly calculate the real-time torque by measuring the eccentricity.The maximum shear stress,torsional angle and first-order natural frequency of the sensor elastomer of different materials are simulated with the ANSYS software.The 17-4PH material with a larger torsional angle and yield limit is used.The central composite design and the Latin hypercube experiment are used to generate different experimental data tables before and after the torque sensor is slotted,and the variance analysis of the experimental data tables is carried out.The multi-objective response surface optimization of torsional angle and first-order natural frequency was also conducted.The optimization results show that the torsional angle obtained with the optimization of the torque sensor without grooving is improved by 15.7%and that the torsional angle obtained with the optimization of the slotted torque sensor is improved by 19.4%.
