Analysis of operating capacity of the motor-axial bearing in components of the wheel-motor block of diesel locomotive E10 made of bronze Br04Ts4C17 and babbit B16

The analysis of failure of traction engine motor-axial bearings is carried out. The methods of motor-axial bearings repair and restoration in locomotive depot and repair shops are shown. Today the decision of problems connected to speed increase, loading, reliability of machine and mechanism components is impossible without application of new materials with special properties created by methods of powder metallurgy.

About a problem statement of a vessel movement rational route and managing influences necessary for its realization

It is devoted to a problem of mathematical model application of vessel movement for the purpose of finding possibility or impossibility of maneuver from given in the given vessel state under available external conditions and for matching of appropriate managing influences. Formal statement of this problem is carried out, the own numerical method is offered, opportunities of its program realization are discussed.

Normalization of reliability and safety characteristics of locomotive systems of interval regulation train operation

The numerical contents of risk and safety of interval regulation locomotive systems are opened. It is shown that the protective failure concept of such systems in travel line can not be applied directly. The analysis is carried out and the dependence numerically connecting the basic characteristics and parameters of locomotive equipment reliability and safety being a measure of its risk is received.

Mathematical methods of machine structural analysis and optimization of production parameters

Construction and optimization questions of structural formulas of technological machines of car-repair plant and freight cars are considered. The algorithm of multistage optimization of a choice of production parameters of car repair which in a combination to machine structural analysis allows investigating the interaction of various depot workshops in a complex is offered.

State modelling of radio-frequency readers of automatic identification system of transport means

The operating regime analysis of a reader of automatic identification system of railway transport means is carried out. Conditions of its operating capacity depending on intensity of the electromagnetic field created by the aerial point of reading are formulated. Recommendations for increase of reliability formed in a reader of an identification sequence are given.

Search of the optimum decision in bridge engineering in the form of a multicriterion problem

It is considered the actual problem of construction of the rational (optimum) decision in bridge engineering during designing transport bridges (a series of bridges or a series of specific designs of these bridges) in the form of a multicriterion problem which optimum decision is determined on two parameters independent from each other.

Bend of three-layer elements of the transport designs connected to the elastic basis

The bend of an elastic rectangular three-layer plate with the rigid filler based on the elastic basis is considered. Kirchhoff hypotheses are accepted for the description of bearing layer kinematics. Reaction of the basis is described by Winkler model. The presence of a rigid diaphragm interfering a relative shift of layers is supposed on a contour of a plate.

Analysis of results of the rated method for determination of concentration fields of polluting substances in a surface layer air

The rated method of an estimation of an atmosphere air state in an influence zone of Il'ich locomotive depot (Moscow - Kievskaya station) is considered. Brief bases and results of method application are given, and also measures on decrease of negative loading on air pool on the part of locomotive depot are offered.
