基于磁弹性原理设计并搭建了扭矩测量实验台，其主要技术指标为：量程0～100N·m、线性度和重复性两个误差指标均为0．1％。扭矩测量结果表明，在磁头与轴不同间隙条件下，扭矩与磁感应强度之间始终存在线性正比例关系，依据这种关系并利用磁力计先测量出磁感应强度值，然后再计算出相应的扭矩值，以实现扭矩的间接测量。

Based on the principle of magneto-elasticity, a torque measurement test bench is built, with main technical indicators as follows： range is from 0 to 100 N·m; the error indicators of linearity and repeatability are both 0.1%. The torque measurement results show that under the conditions of different gaps between magnetic heads and axles, there always exists a linear proportional relationship between torque and magnetic induction, based on which magnetic induction is measured with a magnetometer first and then correspondent torque value is calculated to realize the indirect measurement of torque.
