Maintenance activities mostly depend on the specific conditions of individual equipment, being defined as personalized businesses. In order to improve efficiency maintenance for complex equipment in lots, thinking mass customization is used. After modular technology used generic model, product/service was divided into mandatory and optional modules, which can form multiple service solutions. Co...

Different optimal designs of bogie bolster for model 18-100 freight car are examined in the article. There is an analysis existing designs. Full-fledged fatigue tests by method specified GOST 32400-2013 carried out on stand designed dynamic strength tests. The values experimental studies were compared with calculated ones, maximum loads from 735 to 755 kN. best results observed at a load 745 kN...

The article presents the methodologies based on multi-body systems used to analyze the dynamics of rail vehicle in motion in a straight line. Study of the railway vehicles dynamics requires the creation of three mutually independent models: the model of the vehicle, the track model and a model of the wheel – rail contact. A railway vehicle model developed in the multi-body systems convention w ...

Purpose: To substantiate the circuit design and algorithms for individual smooth automatic control of single-phase direct current electric locomotives according to laws constant traction force power without breaking locomotive circuits in order increase efficiency its drive with controllable motor excitation converters. As a solution, it is proposed apply electrical two rectifier-inverter conve...
