Method and apparatus for the manual non-destructive testing of tubular axle shafts with variable internal and external radius profiles
Abstract:
An apparatus testing axle shafts including i) at least one ultrasonic probe to analyze, in a selected angular sector, selected portions of a wall exhibiting known variable internal and external radius profiles of a tubular axle shaft and thus acquire analysis data, ii) a controller to determine, as a function of the profiles and possible loading and environment of the shaft, at least one first and at least one second selected site on the external or internal surface of the wall where each probe is to be placed manually, to analyze at least one first and at least one second selected portion of the wall respectively in at least one first and at least one second selected angular sector oriented in first and second opposing longitudinal or transverse directions, and thus acquiring analysis data for various relative angular positions of the shaft in relation to the probe, and iii) a processor to create from these acquired analysis data maps representing the transverse or longitudinal orientations and the positions of indications of echoes within the wall.
