Abstract

The invention discloses a Barkhausen array sensor and an imaging method, wherein the sensor comprises a shell; a magnet yoke arranged on the shell and used for conducting magnetism; an encoder arranged on the magnet yoke and used for detecting positional information of the sensor when the sensor is in motion; a Barkhausen receiver array for receiving Barkhausen signals from different positions of material under test, wherein the Barkhausen receiver array includes a plurality of Barkhausen receivers; an exciting coil arranged on the magnet hoke to carry out local magnetization through alternating current. The technical problem that the prior art is unable to provide quick nondestructive detection and imaging for stress distribution of an object under test is solved.

Description

technical field [0001] The invention relates to the detection field, in particular to a Barkhausen array sensor and an imaging method. Background technique [0002] At present, in a large number of engineering sites, stress is ubiquitous. In stress detection, relatively mature methods are X-ray diffraction method and blind hole method. The X-ray diffraction method is accurate in measurement, but the ray radiation is large, and the ray equipment is bulky, which is suitable for laboratory use, but it is inconvenient for on-site use, and it is inconvenient for large parts and transient stress measurement in motion; the blind hole method is passed in the measured A small hole is drilled on the surface of the object, and the internal stress of the object is calculated through the deformation of the area near the small hole, which is destructive to the material and difficult for large-area detection and stress imaging; therefore, there is an urgent need for a method to analyze the...
