Abstract 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.
