Abstract
The present invention provides a dynamic acoustic emission in-situ testing device and method for an electromagnetic rail launcher. The device comprises an armature, a guide rail and a support base, wherein the support base comprises an upper support base and a lower support base which are opposite to each other and are vertically arranged, a distance between the upper support base and the lower support base can be adjusted through bolts, the guide rail is vertically arranged between the upper support base and the lower support base, the armature is clamped in the guide rail, a plurality of groups of static acoustic emission sensors are arranged along the guide rail, a dynamic acoustic emission sensor is arranged on the armature. The method can comprehensively reveal the current-carrying friction damage mechanism of the armature-rail interface under the variable magnetic field intensity condition.
