OBRABOTKA METALLOV

Abstract
The issues of modeling of the technological machines support systems with allowance for technological machines elastic vibrations caused by the compliance of units and limitations of amplitude values of frequencies are considered in the article. The aim of the work is to develop computational models of the technological machine support systems (for example, loom STB) and confirm the proposed computational model by experimental results. It is proved that the computational model of the support system for a loom filling the width of 190 cm may be recommended to determine the first frequency of natural oscillations for the whole range of machines of this type. It is shown that while designing of the machines’ frame works, speed modes of the main shaft operating frequencies and absence of possible resonances should be taken into account. Based on the analysis of machine arrangements of range looms STB the frequency spectrum of the flexural-torsional oscillations of the loom STB -190 support systems is calculated. Developed computational model is a universal range of technological equipment filling the width of 180, 190, 216, 220, 250, 330 cm.
