Abstract

The paper presents the results of the development and implementation of a method for controlling technological processes of locomotive repair based on network planning, which allows monitoring and adjusting the performance of technological operations for a specific locomotive, taking into account the provision of indicators of technological preparation of repair.

Highlights

The increase in the intensity of operation, the increased requirements for the safety of train traffic and the technical condition of the rolling stock impose special requirements on the operational reliability of locomotives.Mainline locomotives operate under conditions of negative impact of dynamic, static loads and vibration, which have a decisive influence on the nature of wear and damage to electrical and mechanical equipment
Severe working conditions are aggravated in winter, when, due to the increase in the rigidity of the rail track, the dynamic acceleration of wheelsets from impacts at the joints reaches 15-20 g
Let us consider a number of criteria typical for assessing the performance of parts and units of traction rolling stock

Summary

Introduction

The increase in the intensity of operation, the increased requirements for the safety of train traffic and the technical condition of the rolling stock impose special requirements on the operational reliability of locomotives.Mainline locomotives operate under conditions of negative impact of dynamic, static loads and vibration, which have a decisive influence on the nature of wear and damage to electrical and mechanical equipment. Assessment of the quality of the operational functioning of structural elements of the metal structure, which include parts and assemblies of the mechanical part of the locomotive (bogies, wheel-motor units (WMU), traction motors, spring suspension, wheelsets, etc.) is carried out on the basis of the following groups of indicators: 1.
