THE EFFECT OF LOCOMOTIVE HOURS ON ADJUSTING PERIODICITY OF MAINTENANCE SERVICE AND CURRENT REPAIR

Abstract

Purpose. The main purpose of this paper is to substantiate the necessity of period adjustment and volumes of maintenance, current repairs of locomotive approaching and regulatory exceeded of their useful operational time. Methodology. In connection with the physical and moral depreciation of rolling stock in modern conditions the most important area to ensure the effectiveness of rail transport in the foreseeable future is the rational use of the rolling stock in operation within the designated and extended service life. At the same time extending the operational time of the locomotives must be achieved by compliance with the optimum ratio of measures to adjust the timing and technology maintenance, current repairs and preparation of repair base. The paper presents the components of dependency forming work amount on maintenance, current repairs with time operation. By the modeling of its changes a graph that implement adjusted system to the content of the rolling stock traction after operation were constructed. The study found that the dynamics of change processes of necessary expenses for maintenance and current repair increases. It is shown that under aging conditions of locomotive fleet and repair base of locomotive economy, a situation that is a critical for the railway transport of Ukraine has appeared. According to it, to the end of operation the amount of work relative to the recommended rules of repair increases slightly. When the locomotive is new or renovated, deviations from the standard path for rigid observance of repair requirements (the compliance with technical standards) does not exceed the norm. However, when the standard period is exhausted, to comply with these standards is not possible. From the data it was found that the greater the amount of maintenance, routine repair in the repair cycle, the more effort you need to put in a multiplicity of software runs between scheduled of maintenance, current repairs. It is advisable to conduct more repair work to ensure lower costs for the maintenance of locomotives. Findings. The values for the effective maintenance of traction rolling stock for a variety of tactics to support them were obtained. Originality. Theoretically the need to adjust the timing and technology maintenance and current repair of traction rolling stock in the operation of locomotives, over normative was demonstrated. Practical value. Obtained results allow increasing the efficient use of traction rolling stock with effectively cost.
