RESEARCH OF HIGH-FREQUENCY CHAOTIC VIRBANCES OF THE WORKING ENVIRONMENT OF VIBROBUNKER

Abstract

In the article the results of researches of high-frequency chaotic vibrational displacements of elements of a working medium (abrasive granules) are considered. It has been established that on the element of a working medium (a part or a granule) that is in a vibrator bunker, there are constant vibration loads with a frequency equal to the frequency of the change in the strength of the electromagnet, which are transmitted from the granule of the abrasive to the part and vice versa. At the same time there is a shock load on the part. For this purpose, a dynamic model of vibration motion of a separate granule is presented, which is presented as three translational partial dynamic subsystems. Their differential equations are constructed and impulse characteristics of a separate granule are found, which include the movement of the granule under the action of the shock load. The general displacement of the granule was found as a superposition of displacement from individual pulsed loads in the form of a set of shock impulses. It was established that the basis of the working process of vibration abrasive treatment is the process of interaction of the parts and granules under the shock loading of the vibrator bunker. The intensity of processing the part depends on its random position at the time of impact.
