The study of dynamics of emissions from road transport in Moscow from 2002 to 2030

Azarov V.K., Vasiliev A.V., Kutenev V.F., Stepanov V.V.


The paper presents the study of materials on emissions from road transport in the major cities on the example of Moscow. It is a forecast of increase of emissions from the growth of the vehicle fleet up to 2030. It was shown significant excess of emissions of harmful solid particles in the exhaust gas, regulated UN rules and general particulate emissions from tire wear, brake systems and road- way, which are currently not regulated. There is the necessity of development of standards for thevaluation of their emissions.

Alternative method of geometric parameters measuring of throttle channels of circular cylindrical shape

Kuznetsov V.S., Yarots V.V.


The use of throttles as elements of control devices in hydraulic drives requires them to ensure the possibility of pressure dependence on the flow of the working fluid of the desired type. To establish this dependence it is necessary to know the area of the opening at the inlet of the throttling passage. However, the direct method to measure the actual value of this area resulting from the manufacture of the throttle channel is not always possible. The article presents the evaluation of the possibility of using the alternative method of determining the area of the entrance to the throttle channel of circu-lar cylindrical shape.

Calculation of contact parameters of loaded body with outer ring raceway in metalpolymer roller bearing

Li R.I., Mironenko A.V.


The method for calculation of contact parameters of loaded body with outer ring raceway in roll- er bearing with polymer coating on outer ring was proposed. The formulas for calculating the pa- rameters of contact were obtained: the width of contact area half-axis and maximum contact stress- es. Computer program for faster and less labor-intensive calculation of contact parameters was de- veloped.
