Aimed to eliminate the lift-off effect on the accuracy of the result of Barkhausen noise detection, this Letter simulated three conditions of the yoke by Ansoft. After studying the simulation results, it proposed a new sensor structure, utilising the mechanical structure of the spring to eliminate the lift-off of the pick-up coil and the BP neural network was adopted to optimise the detected magnetic Barkhausen noise characteristic value. At last, it verifies that the detection error caused by the lift-off of the sensor is reduced effectively.
