摘要
考虑到辊压机工作时设备温度变化范围大、外界干扰强烈等特点,研究了基于磁致伸缩传感器的辊压机压下位移监测及误差补偿方法。通过理论分析和实验手段,对磁致伸缩位移传感器的精度影响因素进行研究。分析了磁致伸缩位移传感器的工作原理,结合传感器实际使用经验,确定外界环境干扰主要是使用环境温度的变化以及电磁干扰的影响,并通过理论分析磁致伸缩位移传感器受温度和电磁干扰的机理。使用最小二乘支持向量机补偿模型,针对温度变化和电磁干扰产生的误差进行补偿。实验研究结果表明,磁致伸缩位移传感器测量精度受使用环境温度和电磁干扰影响较大,使用本文研究的补偿模型后,可以减小温度和电磁干扰对传感器精度的影响。
Considering the wide range of equipment temperature variation and strong external disturbance when the roller press was working,the methods of pressing displacement monitoring and error compensation of roller press based on magnetostrictive sensor were studied,and the influence factors of magnetostrictive displacement sensor accuracy were studied by theoretical analysis and experimental means. Then,the working principle of magnetostrictive displacement sensor was analyzed. Based on the practical experience of sensor,it was determined that the external environment interference was mainly caused by the change of environment temperature and the influence of electromagnetic interference,and the mechanism of magnetostrictive displacement sensor affected by temperature change and electromagnetic interference was analyzed theoretically. Furthermore,the errors caused by temperature change and electromagnetic interference were compensated by the least squares support vector machine compensation model. The results show that the measurement accuracy of magnetostrictive displacement sensor is greatly affected by environment temperature and electromagnetic interference,and the influences of temperature change and electromagnetic interference on the sensor accuracy can be reduced by the above compensation model.
