ОБЕСПЕЧЕНИЕ КАЧЕСТВА МАШИН НА ОСНОВЕ СОВЕРШЕНСТВОВАНИЯ МЕТОДОВ И СРЕДСТВ ОЦЕНКИ ТРИБОТЕХНИЧЕСКИХ ПАРАМЕТРОВ ИХ ФУНКЦИОНАЛЬНЫХ УЗЛОВ

Abstract

The choice of possible ways for machinery quality increase must be based on the investigation results of wear regularities and also on the experimental data obtained in the course of laboratory nature and production method use with the aid corresponding equipment use. 
 The purpose of the work is updating methods and means for the estimate of tribo-technical unit operation parameters. 
 Tribo-technical tests must reproduce a wide range of events taking place at different interactions of machinery surface layers with wear environment under different conditions of operation. The more trustworthy the estimated figures in the course of the experiments carried out, the larger potentialities for quality increase of products manufactured. To obtain reliable data the essential condition is the reproduction of conditions taking place in the course of the operation of the samples under investigation. The modeling of parts wear processes on the plants presented and reproducing wear mechanisms under conditions of operation allows revealing the peculiarities of a contact interaction, wear regularities and defining the efficient ways for parts life increase ensuring proper quality of products manufactured. 
 The methods and equipment developed for tribo-technical parameter estimate allow characterizing more precisely the values of physical stress-strain properties of materials under investigation and sure forecasting the working capacity of friction units under specified conditions of operation.
