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.
Rail vehicle axle-box bearing damage detection considering the intensity of heating alteration
The article observes problems of detection of rolling bearing damages in rail vehicles. Two methods of bearing damage detection are examined – according to heating of axleboxes and by vibro-diagnostic manner. The disadvantage of vibro-diagnostic method is that a contact vibration sensor is used for vibration diagnostics, intervention into rail vehicle structure is required. The method according to heating of axle-boxes also has drawbacks. The same temperature value of axle-box in various conditions may characterize different bearing technical state. The Authors studied a possibility to use temperature change intensity parameters as the diagnostics criteria. Based on the examples of axle-box temperature measurement data, Authors developed and proposed a methodology for detecting axle-box bearings defects. The Authors suggest the use the method according to heating of axle-boxes. The given example proofs that the fact of the presence of their damages can be unambiguously identified by the intensity of temperature change of the axle-boxes.
