    Calculation of contact pressing of a current collector the «aist» taking into account change of aerodynamic carrying power at various climatic conditions and working height

    In article it is made a calculation contact pressing taking into account change of aerodynamic carrying power depending on climatic conditions (in one and a two-phase stream), and as at change of working height of a current collector. Comparison of the received results with experimental data is executed.

    The influence of the shape of the pantograph slide on theaerodynamic characteristics of speed current collectors

    In article aerodynamic properties of SSS87 current collectors intended for the high-speed movement of the electric rolling stock are considered. Spectra are presented of the flow for different shapes of the contact plates. The solution of a problem of modeling of flow of the contact plates of the current collector with the air environment is reached by application of methods of computing hydrodynamics (CFD) the aerodynamic coefficients necessary for calculation of aerodynamic characteristics Are defined. Aerodynamic characteristics of current collectors are constructed.

    Improvement of techniques for laboratory and field tests of the susceptor by controlling the density of the air environment

    In article advanced techniques of laboratory and natural aerodynamic researches of a pantograph and its elements are considered. It is specified that carrying out modeling by means of computational fluid dynamics methods doesn't allow to replace pilot studies completely now. Need of correction of the received results because of influence of change of density of the environment during experimental studies locates. Density of the environment is offered to consider it as an integrated indicator. The main methods of measurement of density of the environment are given, their advantages and shortcomings are listed. The conclusion is drawn that it is most expedient to use ultrasonic measuring instruments to control of an indicator of density. The principle of operation of these measuring instruments is described. The example of use of an advanced technique of laboratory researches of the aerodynamic device for regulation of force of contact pressing of a current collector is given. Researches were conducted for device wing angles of rotation from zero to fifteen degrees with an interval of five degrees. After that aerodynamic characteristics of a wing of the aerodynamic device were under construction and comparison to results of modeling was carried out by means of a computing hydraulic gas dynamics them. The results received in OSTU laboratory well were correlated with results of computational fluid dynamics modeling that testified to adequacy of the applied technique.
