| Abstract: | Based on the magnetic field, magnetic path, magnetoresistance and magnetic field distribution theory, the design specifications of special tooling for magnetic particle detection of the parts with small slenderness ratio are proposed. The tooling obviously improved the sensitivity of magnetic particle detection for engine frame parts. The detection technology has already been applied to the nondestructive detection of the engines. |
