一、前言在一切动力传递系统中,利用扭矩传感器对扭矩或转矩进行监测,对于保证系统的安全运行,提高效率,降低能耗等都具有重要意义,特别在系统采用计算机进行控制的场合,传感器作为“感官”更是不可缺少的重要仪表。所以,人们一直在努力地探索和创造各种类型的扭矩传感器。已经广泛使用着的有应变片式,扭转角式扭矩传感器等等。这些传感器虽在一定场合能满足使用需要,但均存在着测试可靠性低、体积大、易磨损、造价高等缺点,限制了其使用。为了更好地解决这些问题,我们研制了一种新型的扭矩传感器——TK型磁弹性扭矩传感器。 TK型磁弹性扭矩传感器以非晶态软磁合金作为 I. INTRODUCTION In all power transmission systems, the use of torque sensors to monitor torque or torque has important meanings for ensuring the safe operation of the system, improving efficiency and reducing energy consumption. Especially when the system is controlled by a computer, Sensors as “senses” is an indispensable instrument. Therefore, people have been trying hard to explore and create various types of torque sensors. Has been widely used with strain gauge, torsion angle torque sensor and so on. Although these sensors can meet the needs of use on certain occasions, they all have the disadvantage of low reliability, large volume, easy wear and high cost, which limits their use. In order to better solve these problems, we have developed a new type of torque sensor - TK magnetic elastic torque sensor. TK magnetic elastic torque sensor to amorphous soft magnetic alloy as
