Ultrasonic Tomography of Press-Fit Joints

Abstract

Amethod of studying press-fitjoints using ultrasonic tomography is developed. A possibility of obtaining the gray level image of the strain-stress area of the press-fit joint by means of software assets (i.e., through synthesis of 3D-image (3D-tomograms) of the joint using circular diagrams of the object “cross-sections” (2D-tomograms) drawed by multiangle supersonic sounding. An emphasis is made on the possibility of reconstructing 3D-image of the area under study directly from the results of measurement without any additional mathematical treatment. Special attention is paid to the clarity, illustrative character of the developed method, and extension of applications to automation of the quality control of the joints.
