Verfahren und Vorrichtung zur beruehrungsfreien Messung mechanischer Spannungen an schnell bewegten Objekten mit kristalliner Struktur

摘要

In a process for contactless measurement of mechanical stresses on rapidly moving objects, an analyzing crYstal (A) and a detector (B) are arranged in a housing (H) and are pivoted together at a fixed angle to each other along an arc of a circle of a goniometer about the test object (S). The variation of the grating constants of the test object and the resultant stress are derived from the difference between the angles of diffraction (2) measured in the absence of stresses and in the presence of stresses.
