摘要：

微扭矩传感器适用于微小扭矩测量,具有测量精度高、分辨率高和不确定度小等特性。常规的扭矩传感器校准仪常采用悬臂梁加砝码的结构,结构简单,稳定性好,但也存在摩擦阻力矩等干扰因素,难以满足微扭矩传感器计量校准。一种新型微扭矩传感器校准仪在原有悬臂梁加砝码的结构基础上,垂直放置扭矩传感器,并采用磁悬浮结构、纯扭矩加载方式和轻质复合材料,极大消除了摩擦阻力矩等干扰因素的负面影响,提高了测量精度。

Abstract: Micro-torque sensor which is used in the field of micro torque measurement,has the properties of high measurement precision, high resolution and small uncertainty. Traditional calibrator, which adopts the structure of cantilever and weight, has the advantages of simple structure and good stability. But it also has the disadvantage of frictional torque, can not satisfy the calibration of small torque sensors. A new micro torque sensor calibrator has been designed, which is based on traditional structure of cantilever and weight. It adopts magnetic suspending structure, pure torque-lording and light composite materials, and the torque sensor is vertically placed, which greatly eliminates interfering factors such as frictional torque and hugely improves the measurement precision.
