The reliability analysis of combined harvesters in the usual conditions of operation

Abstract

The article reflects the results of operational tests of grain harvesters of various years of production of both domestic and imported production in the farms of the Stavropol Territory. In recent years more equipment has been purchased, but its numerical volumes are still small and do not cover the needs of rural commodity producers. Consequently, the work is mainly carried out on old and worn-out equipment, which, in turn, causes an increase in the wear and tear of the farm's agricultural enterprises. Reduction of combine harvesters and, as a result, increased loads on them leads to a significant increase in the share of failures of these agricultural machines. The duration of harvesting grain directly depends on the number of combine harvesters, their reliability and productivity. The level of reliability of grain harvesters was estimated based on the results of continuous and selective timing of the work of agricultural machines. The specific weight and significance of each of the components of the averaged shift time balance are described. It is established that the productivity of combines with the proper level of maintenance does not depend on the period of their operation.

Research of Alternative Options for Strengthening Surface Treatment of Cast Iron Products

“…Requirement strengthening to material will stimulate manufacturers to improve the operational properties of metals and master new types of products. It is important to prevent failures associated with wear and tear of the main structural elements for quality improvement of equipment operation, which includes products working in friction conditions [4,5,6]. The problem of increased wear arises due to the fact that the workpiece surface is under real loads and it is subjected to corrosion [7,8].…”
