Construction of a mathematical model of the process gas outflow through small body opening boiler railroad tank cars

The paper describes a mathematical model of gas-dynamic movement through the through defects in the body of the boiler tank cars. The mathematical model allows to take into account the processes of gas flow at low pressure drop and the impact of the level of roughness of the inner surface of the through channel formation jet escaping gas. The comparison of the results of theoretical modeling and experimental studies of the velocity of the gas flow and temperature under different conditions. The study identified the laws of gas flow through a series of classic models through defects. Shows the dependence of the temperature of the escaping gas flow from the exhaust velocity and the level of roughness of the internal surface of the through channel, which allows us to estimate the nature of gas flow and temperature gradient. The obtained results allow to adjust the level of sensitivity to rejection temperature during thermal leakage control boilers railway tanks.

Numerical study of thermal contact processes gidrofriktsionnom vibration dampersfor high speed electric rolling

The article proposes a numerical-analytical method based on the boundary element method (Method of Boundary Elements Technology), which used to assess of change patterns of temperature fields in the working fluid in hydro-friction vibration damper telescopic view when the ambient temperature changes. This method takes into account the physico-mechanical properties of the working fluid and the effect of corrosion pouring temperature, ambient temperature, the speed of electric rolling stock and the working liquid filling height.

Optimization of graphic time-table to the criterion of electrical energy’s expenditure for traction on the railways sections in the conditions of using the regenerative braking

A method to an assessment of influence on the expenditure of electrical energy for traction of trains, parameters of graphic time-table in the conditions of using the regenerative braking is being considered in the article. The retrieval of version with the minimal using of energy is based on the modeling of graphic time-table by different train-to-train intervals in the conditions of burst-mode access’ organization on the railway section. By results of modeling it is proposed to represent the derived dependence by changing of electrical energy’s expenditure on parameters of graphic time-table in the form of analytic function of several variables n-order forthe following using by normative plotting of movement for the purpose of curtailing electrical energy’s expenditure for traction on the trains.

Assessment of operational characteristics of transport knot

In article the problem of determination of length of turn of structures, the total loading capacity of the transport which isn't provided with freight, quantity of freight of the transport knot which is in a timepoint in a warehouse on the basis of definition of distribution of a random variable of the freight expecting loading or unloading, and also the free capacity of vehicles taking into account restrictions on the capacity of warehouses is considered. During the solution of a task the following assumptions are accepted: capacity of cargo handling devices of transport knot isn't limited; time of the translation of giving of cars for the pogruzoch-but-unloading front and back isn't considered. The structure is understood as conditional structure which loading capacity is equal to the total loading capacity of some party of real structures, and the moment of its arrival - to the arrival moment on transport knot of the last of them. The received results can be used for determination of optimum values of warehouse capacities and a technological stock of freight of transport knot at the set goods turnover.
