Basis of local life extension method insulation of electric machines of locomotives thermal radiation

The main damaged knot of traction electric motors of a traction rolling stock is isolation, namely in the field of the basis of front part. The imperfect system of isolation in face part of front windings results in humidity. Also the increased intensity in this zone is the reason of low reliability. Authors propose the system of local insulation encapsulation energy of infrared radiation as life extension activities of electrical machines.

Unevenness of working process and fuel supply as diagnostic indicators of diesel engines working on different fuel grades

Theoretical analyze of liquid fuel movement in low-pressure line (LPL) of diesel fuel supply systems is implemented. To solve LPL the equations set of homogeneous blend is suggested. It is shown that when using alternative fuels in locomotive and ship diesels the retrimming of fuel equipment is required, and it’s reasonable to use the degree of irregularity of working process as diagnostic indicator.

Modeling clean contact between the contact wires and collector strip with static finite element methods

In the article the finite element model of the electrical contact pin wire - collector strip, which takes into account the complex interaction of electric and thermal processes. As the contact wire is selected worn MF-100, the current collection plate - two brands VJZ-metal and graphite. Microgeometry the body surface at the contact point is obtained based on the model of Greenwood - Williamson. It was considered the two extreme cases of possible contact between the contact wire to the plate. The results were analyzed and compared with the known experimental data. Calculated at what proportions contact force and contact current due to burnout occurs spark or arc. Identify ways to improve the model.

Shielding effectiveness calculation method for the radioelectronic equipment in case of pulse electromagnetic field impact

In this article a shielding effectiveness calculation method for the radio electronic equipment is considered. Monolayer and multilayer shields made with aluminum, cuprum, steel is investigated. Interaction of pulse magnetic field and conductive shield is simulated using finite difference time domain method. Frequency and time dependencies for the shield impedances are shown. Also pictures of electromagnetic field distribution near shielding are presented. Time dependencies of electric field on the shield external and internal borders are shown.

Improved method of calculation tensity of permanent tunnel lining with temporary shotcrete lining factor

Shotcrete lining is one of the most common types of temporary supports in tunnel construction. The influence of shotcrete lining on design calculations of permanent lining is difficult, because there is no method of designing at the present time. This leads to increasing in consumption of materials and labour of construction. The information about the influence of the basic mechanical properties of soils, geometrical size of construction per value of temporary shotcrete lining factor was obtained during research. These data formed the basis for futher development method of designing. Empirical correlations of stress distribution between temporary shotcrete lining and permanent monolithic reinforced concrete lining were obtained during theoretical research. Results of experimental research tensity of temporary shotcrete and permanent lining confirmed the possibility of using in the designing this empirical correlations. Using in the designing proposed empirical correlations will leads to reduction in consumption of materials and labour of construction.

Cas of keeping of inside factory claotype transport

On an inside factory industrial transport different transporting machines (railway faucets, motovozy, electric locomotives and other), moving on a claotype way, are used. For realization of the required manipulation loads the transporting machines indicated higher must be stopped at one or another points (positions) of claotype way with high enough exactness, that is provided with a help. The analysis of existent control system rotined that they provided exactness of keeping of transporting machines not always. For the increase of exactness of the system of the automated keeping, oriented to application on an inside factory claotype railway transport technical solution, protected patent of Russian Federation.
