An optimization model of traction rolling stock operation

Working with market terms and conditions, matters (issues or questions) regarding stocktaking (registration) of property (resources) and rational usage are very urgent. Economical effect is perceived as tax, the difference is got by the transportation of carriage and exploitation cost. The mathematical model is formed by three components. The receipts or income (affirmative and positive component), fuel cost and cost a time (negative component). The difference of streams of loads is very import. This mathematical model is supposed to improve the transport income for each transported carriage unit, the cost of fuel and other exploitation costs and to evaluate the difference of streams of loads.

The analysis of wear intensity of the locomotive wheel - sets

The wear dynamics of wheel - set tyres of Diesel locomotives was investigated. Based on the results obtained, it is possible to forecast the safe operation period of wheel - set tyres between overhauls, to improve their maintenance and planning of overhauls and to achieve more efficient allocation of resources to the repairs of traction rolling stocks.

Determining the efficient service life of traction rolling stocks

To maintain and renew traction rolling stocks, the causes of their deterioration which are closely connected with operational conditions should be identified. For this purpose, such parameters of rolling stocks as the performed work, speed, acceleration, mass, etc. should be properly determined. The first objective is to develop mathematical models to evaluate integrated criteria describing the deterioration of freight and passenger locomotives from technical and economical perspectives. The second goal is to compare the main criteria describing the process of deterioration of freight and passenger locomotives and the respective differences in the strategies of their renewal. Fuel consumption, engine oil consumption and terminal delays due to off-schedule locomotive maintenance were investigated. Each of these parameters may be used to determine the locomotive state (quality) from a particular perspective.

Zmiana złożonych wskaźników gospodarczych zużycia osobowego taboru kolejowego

Szereg kryteriów opisujących stan lokomotywy z różnych perspektyw może być używanych do oszacowania ich stanu. Kilka złożonych albo zintegrowanych kryteriów obrazujących stan ogólny lokomotyw Diesla może też być alternatywnie używanych w takim przypadku. Zintegrowany wskaźnik wyników charakteryzujący stan lokomotyw może być wyrażony przez opisane funkcjonalne zależności. Analiza dostępnych metod dla złożonej oceny stanu taboru kolejowego pokazała, że wydajność całkowita lokomotywy może być opisana przez bezwymiarowy wskaźnik.

A change of complex economic indicators of passenger rolling stock deterioration

Various criteria describing the state of a locomotive from various perspectives can be used to assess its performance. Some complex or integrated criteria reflecting a general state of Diesel locomotives can also be used. an integrated performance indicator characterizing the locomotive performance is expressed by the following functional relationship. The analysis of the available methods for complex evaluation of the locomotive condition has shown that overall performance of the locomotive can be described by a dimensionless indicator.

Model matematyczny wahań przestrzennych wagonu pasażerskiego

Dla komfortu podróżnych i dla zapewnienia trwałości części i zespołów taboru kolejowego niezbędnym jest wybór racjonalnych parametrów zawieszenia podwozia, tj. ustalić racjonalne stosunki pomiędzy dwoma elementami sztywności stopni zawieszenia i tłumienia drgań. Niniejszy artykuł jest przeznaczony dla stworzenia przestrzennego modelu matematycznego, gdy istnieje zawieszenia z dwoma stopniami i różnymi elementami sztywności. Opracowany system równań posiada 52 stopnie swobody. Przedstawiony model matematyczny może byś stosowany dla ustalenia rzeczywistych obciążeń dynamicznych wagonów pasażerskich i przez to do wyboru racjonalnych parametrów krótkich zawieszeń.

Mathematical model of spatial fluctuations of passenger wagon

To ensure passenger comfort as well as the durability of the components of rolling stock, it is necessary to determine the rational parameters of chassis suspension, i.e. rational relations between rigidity and vibration inhibition elements of the two stages of chassis suspension. The article describes a spatial mathematical model of a two-stage suspension that has different rigidity elements. The equation system created has 52 degrees of freedom. The model presented in this article can be employed to establish the real dynamic load of passenger wagons and to determine the rational parameters of resilient suspension.
