Термомеханическая модель возбуждения автоколебаний при обработке металлов резанием

Термомеханическая модель возбуждения автоколебаний при обработке металлов резанием

Abstract

A hypothesis about the thermal-mechanical nature of self-oscillations of metals machined by cutting is introduced, that makes it possible to generalize the main available models of this effect. Based on the hypothesis, an analytical and a numerical models of excitation of self-vibrations are developed. The adequacy of the results obtained is corroborated by the results of realistic experiments.

Предложена гипотеза о термомеханической природе автоколебаний при обработке металлов резанием, позволяющая обобщить основные известные модели этого явления. На основе предложенной гипотезы разработаны аналитическая и численная модели возбуждения автоколебаний. Адекватность полученных результатов подтверждается результатами натурных экспериментов.
