Prediction methodology of durability of locomotives diesel engines

Abstract

The article testifies that technical maintenance and repair terms as well as durability can be predicted accordingly to the maintenance parameters of the diesel locomotives. It is determined that fixing fuel consumption and capacity of diesel locomotives and taking in comparison with limit values allows to set a performance date for technical maintenance. Introduced suggested aspects of interrepair resource of the diesels dependent on comparable fuel consumption and evaluating their operating probability without failure for the durability prediction of diesel locomotives. Currently, the most common are three strategies: until failure, scheduled – premonitory and adaptive (diagnostic). When the quantity of necessary technical maintenances is known for the specific kind of diesel locomotives it is possible to determine interrepair resource depending on comparative and required per hour consumption of fuel and predict their durability taking into account probability of operating without failures.
