PROBABILISTIC MODELING IN STUDIES OF THE ACCURACY THE MANUFACTURE OF ENGINEERING PRODUCTS

Abstract

Methodological aspects of the theory of precision Assembly operations in the manufacture of engineering products. Substantiated the advantage of probabilistic modeling in engineering. Noted that the primary error of engineering products change over time because of wear and tear, as a result of what is happening in the material details of the physical-mechanical processes, and experimental study of the marked character of changes in parameters of the parts does not give the exhaustive information on which to judge those or other reliable regularities of the phenomena. It is noted that the experimental study is very important, as allows to receive multiple implementations, which can be seen on the character of changes of primary errors in particular cases. The features of the use of probabilistic modeling in solving problems of the nonlinear theory of accuracy.
