Abstract
The article tells of the method of pressure coupling fit area research with ultrasonic tomography, which was set up on the basis of the proprietary technology of quantitative estimation of press-fit joints quality with the ultrasonic echo-impulse method. The possibility of 3D - images receiving of the press-fit joint strain-stress state area is shown. On the basis of the study of the characteristics of ultrasound reflection from the pressure coupling fit area, it is shown that the ultrasonic signal reflection coefficient is the general characteristics of press-fit joint quality because it is bound with the normal stresses appearing on the joint surfaces. Considerable attention is paid by the authors to the possibility of optimization of the research process: the possibility of automation of joint quality control by the described method is realized.
