摘要
新型扭矩传感器的开发一直是国内外众多专家学者研究的重点,提出了一种基于逆磁致伸缩效应的扭矩传感器,它利用粘贴在轴上的高磁致伸缩非晶态合金层代替轴本身作为应力敏感元件。此传感器可安装在旋转轴上,而固定的测量仪器采用磁性耦合技术,可避免滑动接触。实验论证了传感器的基本特性,结果表明传感器具有检测扭矩的能力。
The development of new types of torque sensors has been one of the key issues that involve the efforts of many experts. In this paper, we proposed a torque sensor based on magnetostrictive effect, in which the reverse-magnetostrictive layer stuck on the rotating shaft surface instead of the shaft itself is used as the sensitivity element. The sensor can be installed on shafts and the stationary measuring equipments are magnetically coupled, thus can avoid slipping contacts. The static and dynamic characteristics of the sensor have been tested and results show that the designed sensor can efficiently detect torques.
