项目摘要

In order to develop a magnetostrictive torque sensor using a steel shaft, factors affecting the accuracy of the sensor, such as magnetic inhomogeneity at the surface of the shaft which causes zero-level-fluctuation with shaft rotation and hysteresis in the input-output relationship, are investigated for several promising steel shaft svailable commercially. We examined, using magnetic heads with figure of eight coils, nickel-chromium-molybdenum steel shafts such as SNCM420, SNCM616 and SNCM447, and chromium-molybdenum steel shafts SCM420. The sensitivity was highest with SNCM616 and then SNCM420/SNCM447 following this, finally SCM420 when these shafts were casehardened. The input-output hysteresis is analyzed for the magnetostrictive shaft torque sensor with phase-sensitive-detection. We describe a method of tuning operating condition of the torque sensor to obtain zero hysteresis for a class of the steel shaft. We found that the lowest hysteresis was obtained with a carburized SNCM420 shaft at the excitation condition of 60 kHz 0.3 A.The linearity measured with this shaft was as good as 0.8% (full scale=1000 Nm for a shaft of 25 mm in diameter). The zero-level-fluctuation of the torque sensor using SNCM420 carburized shaft was (]SY.+-。[)1.3% (full scale). We further established a method to select a proper steel shaft yielding zero hysteresis.We also developed a method of imaging surface anomaly using a miniaturized magnetic anisotropy probe. Using this, we found helical patterns of inhomogeneities at the surface of unheat-treated shafts which were probably induced during a final stage of steel bar manufacturing process.
为了研制一种钢轴磁致伸缩扭矩传感器,针对几种有市场前景的钢轴,研究了影响传感器精度的因素,如轴表面的磁不均造成随轴旋转的零电平波动和输入输出关系中的滞后。我们用八线圈磁头检测了SNCM420、SNCM616和SNCM447等镍铬钼钢轴和SCM420铬钼钢轴。对SNCM616的敏感性最高,其次是SNCM420/SNCM447,最后是SCM420。分析了相敏检测型磁致伸缩轴扭矩传感器的输入输出滞后性。我们描述了一种调整扭矩传感器工作状态以获得一类钢轴零滞后的方法。结果表明,当激励频率为60 kHz0.3A时,渗碳SNCM420轴的磁滞回线最小,测得的线性度为0.8%(直径25 mm的轴满量程为1000 Nm)。采用SNCM420渗碳轴的扭矩传感器的零电平波动为(+-)。[)1.3%(满分)。我们进一步建立了选择合适的零滞回钢轴的方法,并发展了一种利用微型磁各向异性探头对表面异常进行成像的方法。利用这一点,我们发现了未经热处理的轴表面的螺旋状不均匀图案,这些不均匀可能是在钢筋制造过程的最后阶段诱导的。
