AbstractsM.V.Soldatov, A.V.Karelina It is shown that the qualitative information describing useful effect, total costs for life cycle of objects is necessary for measurement of competitiveness of an analyzed object. Z.V. Abuseridze The development questions of micromotors with a solid ferromagnetic rotor, such as definition of solid rotor parameters and optimum material and design matching of a solid rotor are considered. Results of the calculation are given. P.A. Kozlov, I.P.Vladimirskaya The properties of transport systems determined by interaction of traffic flow and structure, structure elements and subsystems are considered. Structural interaction shows a coordination degree of elements. Calculation of complex structure assumes consideration of many variants, the special method of optimization is necessary. A.D. Hamoev Questions of speed restriction of breakdown railway cranes of various carrying capacity, formation of endurance cracks in beams of a bogie frame, and definition of operating time of cranes are considered. M.V. Gryaznov Influence of reservation process of spare parts on efficiency and reliability of a motor-vehicle fleet is designated. It is revealed that negative influence on functioning of a motor-vehicle fleet renders imperfection of spare capacity norms. For increase of planning reliability of spare deliveries and also reduction of their dead stocks in a warehouse the author offers a substantiation technique of a spare parts' reserve based on use of nomenclature norms. S.Yu. Eliseev, V.M. Nikolashin, E.P. Shmuglyakov The concept of creation of the coordinated-logistical centres in the transport nodal points working in single information field is considered. The concept of the coordinated-logistical centre of transport nodal point is stated; its role and place in logistical system are shown. Principles of technological coordination of related kinds of transport in transport nodal points on all extent of a circuit of goods promotion from the producer up to the consumer are examined. Yu.A. Kravtsov, V.I. Lin'kov, P.E. Mashchenko, E.G. Shcherbina, A.E.Shcherbina Influence research of technological disorder of the form of frequency characteristics of entrance resistance of track receiving sets of voice-frequency track circuits on settlement factor of return by results of which the measurement technique solving a problem of metrological maintenance of rail circuits of voice-frequency is made. As the technique is offered, allowing to carry out correct calculation of track circuits of voice-frequency in view of technological disorder of the form of frequency characteristics of entrance resistance of track receiving sets. S.A. Ul'janov The major aspect of city passenger transport - maintenance of steady functioning is considered at unconditional observance of safety requirements. Operative reorganization and exact performance of the routing diagram of vehicles in conditions of the allocated lanes demand construction of the centralized automated control of ground city passenger transport. E.A. Popova It is submitted multiple-factor grapho-analytical method of train handling process at single-track lines in conditions of their lining with overtaking slow-acting trains by freight trains with a view of more exact estimation of group of freight trains' coefficient. Formulas for definition of group of freight trains' coefficient depending on conditions of functioning of a railway site are received. A.A. Astahov, V.P. Anan'ev
Prospects of discrete digital and analog information transfer in conditions of extreme situations on railways are
considered. Research of pulse handicaps on electrified railways of a contact network and construction of spectrogram
P.A. Nevarov
The method of the analysis of efficiency of operating efficiency of railway automatics and telemechanics systems
is considered on the basis of principles of the queuing theory having regard to train operation process.
N.A. Taradin
The mathematical model for an estimation of traffic safety on a railway crossing is considered. The comparison
technique of efficiency of various traffic safety systems on a railway crossing under certain operation conditions
is offered.
L.A.Osipov
The common formulas of account of parameters of efficiency of multichannel systems of mass service (SMS)
with final stores for turns are developed: an average holding time of the applications, share of refusals, degree of
loading of a processing part. On the basis of it the algorithm of definition of rational parameters and structures
projected SMS is given. All accounts are made without calculation of probabilities of condition of system through
relative loading on SMS.
L.A. Baranov, A.N. Savos'kin, O.E. Pudovikov
The new structure of automatic control system of driving speed is offered. It allows essentially to lower sizes of
the longitudinal dynamic forces arising in a train in modes of traction and electric braking.
D.V. Osipov
The quality estimation of manufacturing of details at various factories by methods of cluster, retrogression and
correlation analysis by results of acceptance nondestructive test of big cogwheels of traction transfer of electric
trains is carried out. The analysis of constructional materials used for big cogwheels manufacturing is done, and
the material having the best operational properties is revealed.
L.G. Kopteva, V.A. Nozhnov
Requirements to an adapted intellectual simulator are formulated; the analysis of its models is made. Recommendations
for their practical realization are given. Flexibly adjusted structure of an intellectual simulator is
developed.
I.V. Vol'hin, V.D. Katin
Essentially new circuits of the installations are offered. They allow to be going water-black oil emulsion from
waste water and water with oil products on the boiler enterprises of the Far East railway with the purpose of
the further effective combustion. Recommended circuits permit essentially to lower emissions of polluting substances
in combustion products and to solve important environmental problems of recycling of the polluted
waters without expensive clearing.
