摘　　要：动态扭矩的检测对于旋转动力设备的运行起到很重要的作用,通过实时检测设备工作时的扭矩,可以间接分析出设备的工作状态。设计了一款非接触式的动态扭矩传感器,其可以通过测量偏心距来间接计算出实时扭矩。利用ANSYS软件仿真了不同材料下传感器弹性体的最大切应力,扭转角度和1阶固有频率,选出扭转角度和屈服极限较大的17-4PH材料。采用中心复合实验和拉丁超立方实验的方法对传感器开槽前后生成不同的实验数据表,并对实验数据进行了方差分析。针对扭转角度和1阶固有频率进行多目标响应面优化,优化结果表明:没有开槽的传感器进行优化得到的扭转角度提高了15.7%,开槽后的传感器得到的扭转角度提高了19.4%。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%.
