| Abstract: | The in-service detection of fatigue defects on the surface of aluminum alloy parts of railway traction motor cannot be carried out by penetration method due to the limitation of conditions.This paper introduces the process and test parameters of the eddy current high frequency shield probe for the detection of the surface defects of the key parts of the motor end cover under the condition that the surface is not depainted,and explains the actual detection effect. |
