METHODOLOGICAL BASES OF RESEARCH OF RELIABILITY OF OPERATION OF QUARRY DUMP TRUCK COMPONENTS DURING THEIR OPERATION

Abstract

The article considers the indicators of quantitative assessment of reliability of components operation in the process of dump trucks operation in mining enterprises. The basic concepts, terms and designations of reliability assessment indicators are given, and also formulas and expression determining the reliability of dump trucks are given. The histogram of determining the degree of exploitation of dump trucks at the enterprises is given. In this work, for mechanical, hydraulic and electrical equipment in general, for the investigated dump trucks, the reliable amount of data on failures was determined based on the assumption of exponential law of distribution of operating time between failures. At the same time, estimates of reliability indices of individual elements were obtained with confidence probability.
