FIELD: measurement equipment.SUBSTANCE: sticky foil from plastic metal is used, for instance, aluminium scotch tape. Foil is cut into fragments, stretched within the limits of elastic deformations, and in this condition, using a sticky foil layer, it is applied onto controlled surfaces of parts. Tail sections of fragments are rigidly fixed on the surface of the part with a mechanical or another available method. Afterwards in the transverse plane in the middle of the foil fragment length they make through slots and holes.EFFECT: expanded arsenal of technical facilities to monitor cyclic deformations of machine parts that arise in process of their operation, higher efficiency of control due to increased sensitivity of sensors to low values of cyclic deformations.3 dwg |
