一种振动转矩传感器标定方法研究

提出了一种标定振动转矩传感器的方法。标定系统包括振动转矩激励源、振动转矩传感器和可调负载,工作时3者同轴相连。振动转矩激励源通电后产生的电磁转矩包括恒定分量和振动分量,且两者的幅值大小相同,因此,标定系统稳态运行时,根据转矩平衡方程可知,负载值与振动转矩的幅值相同,通过记录振动转矩传感器的输出电压和负载值即可实现标定。最后对振动转矩传感器进行了标定实验,振动转矩传感器的灵敏度系数达到4.58V/(N·m)。

Study on A Novel Calibration Method for Vibration Torque Sensor

A novel calibration method for vibration torque sensor is presented. The calibration system includes vibration torque excitation source,vibration torque sensor and adjusting load, which are connected coaxially in operating. The electromagnetic torque of vibration torque excitation source generates constant component and vibration component, of which both amplitudes are the same. Therefore, the value of load and the amplitude of vibration torque are same when the calibration system is in steady operation according to the torque balance equation. The vibration torque sensor can be calibrated by recording the load value. The vibration torque sensor was calibrated by experiment, and the corresponding performance indicators are received, which verified the feasibility of the calibration method.
