Method for the determination of the processing quality of repair parts of agricultural machinery

Abstract

The dependence of the technological system state of repair equipment during its operation on the quality of repair of machine parts is revealed. The authors proposed a method to determine the quality of processing of repair parts, including ones of transfer function of the movable friction unit along the sliding guides of the metal-cutting machine under conditions of semi-fluid (mixed) friction in the form of an equivalent oscillatory link. The method is based on the integrated method for calculating and determining the technical state of a typical repair equipment based on the proposed integral criterion for the assessment of its vibration resistance. Using the theoretical developments and experimental data, the transfer functions of the machine support system for various designs were determined. The proposed complex method to calculate and determine the technical state of standard repair equipment will make it possible to develop new design solutions and re-equip the existing machine park of repair enterprises in agro-industrial complex.
