Computer holography - a means of determining the technical state of agricultural and forest machinery

Abstract

The question of the implementation of computer holography as a means to determine the acceptable technical condition of parts of agricultural machines as a method of non-destructive testing. Examples of holograms and mathematical model surface mikrodeformation details. Minimum microstrains and according to a minimum of tensions areas answer with the minimum recreated intensity of light stripes. On computer holograms these stripes of midrange of light spectrum, on what scales specify resulted on holograms. Studying holograms for every type of loading and as details. Displacement of the coloured stripes on a hologram testifies to the presence of damages or defects. The dramatic change of color also gives information about the presence of damages or defects. As be set by an experimental way, the presence of concentrator of tensions, remaining tensions testifies to being of defect under a concrete surface. The results of experimental researches that is characterized stability of computer holograms serve about these determinations. During realization of researches, for example: elements of досліджуємої detail with 25 multiple repeated, a computer hologram fixed a similar picture practically, that gave an opportunity to assert, this detail is made without present defects, has parameters within the limits of possible and can be effectively exploited on the draught of certain period of time. Researches conducted with the use of ploughshares of ploughs, that is used for treatment of soil in agricultural and лісогосподарських enterprises.
