Study of the technological parameters of thermal influence for the mating parts with CTMA

Abstract

In to the article are given the results of theoretical studies, on the basis which are obtained new scientific approaches to the development of methodology and calculated dependences for determining the technological parameters of mating parts on the operation of their uneven heating and low-temperature cooling. After accepting for the basis the methods of the theory of elasticity and thermal conductivity, the author scientifically substantiated the fundamental solutions, which will make it possible to obtain analytical dependences for determining the changes in the fit diameters of mating parts with CTMA. On their basis will be occurred the possibility to develop design models for determining the temperature parameters, changed in the time and ensuring the guarantee of fulfilling of technological process of assembling connections with the interference with the presence of temporary assembly-line clearance.
