Analiza harmoniczna i metodyka wyznaczania odchy?ek kszta?tu oraz odchy?ek po?o?enia osi zespo?u powierzchni cylindrycznych z wykorzystaniem komputerowego programu DEVFORMLOC-NK?N
W artykule przedstawiona zosta?a metodyka pomiaru i wyznaczania odchy?ek kszta?tu oraz po?o?enia osi wed?ug elementu ?redniokwadrato-wego, dla zespo?u powierzchni cylindrycznych obiektu ustalonego w dwóch pryzmach. W metodyce tej wykorzystane zosta?y elementy teorii analizy harmonicznej zarysów okr?g?o?ci. Przedstawiony zosta? równie? autorki program obliczeniowy realizuj?cy obliczenia wed?ug zaproponowanej metodyki.%Measurements of geometrical errors of large size cylindrical machinery parts based in V-blocks belong to a group of the so-called reference measurements. During them a based element is displaced. The existing mathematical models, developed for a case of basing the detail in a single V-block, make it possible to transform the measured shape into the so-called transformed real shape as well as to determine unknown parameters of the measured roundness shape [4]. The paper presents the method for measuring and determining the shape deviations as well as axis location of the measured system of surfaces of cylindrical machinery parts based in two V-blocks. For measurements of this kind there was worked out a mathematical model, based on the theory of roundness shape harmonic analysis, for transformation from the measured to transformed real shape [6]. The mentioned model makes it possible to express harmonic components of the real shape as a function of parameters of the measured detail and measuring system. As a final result, there was developed by author the computer program DEVFORMLOC-NKLN by the author. It is destined for numerical computations of estimated parameters of the measured cylindrical surfaces system and presented in the paper asa flow-chart.
