Method and apparatus intended to the suppression of unstable residual internal strains and to the dimensional stabilization of parts made of solid materials and having a crystalline structure. To this effect, the apparatus is formed of an excitation stage, an analysis stage and a computer which interprets the analysed signal and, as a function of the latter, controls the excitation stage, the result being visualized on a display and graphically recorded on a diagram-certificate of quality. The vibration rule is preset in the form of a program in the memory of the computer or set on site. The apparatus may be embodied as a movable unit for large parts or alternatively as a stationary unit for small parts, the relief being effected at the optimum location from the point of view of the user. |
