Abstract

The method of increasing the coupling of locomotive wheels with rails based on the effect of magnetic fields on the contact area is considered in this paper. Moreover, the designs of the magnetic coupling amplifiers of locomotive wheels with rails in chordal, axial and central positioning of the inductor are analyzed. The magnetic equivalent circuits of a three-axis and two-axis locomotive bogies equipped with inductor coils are constructed. The comparison of magnetic the coupling amplifiers is carried out, the main structural and operational advantages and disadvantages of each principle of the inductor arrangement are given. Thus, axial and central positioning of the inductor is the most suitable for the magnetic coupling amplifiers. The model is constructed and the parameters of the magnetic field are determined by using the software Ansys Maxwell, the magnetomotive force and the inductor power are calculated to achieve a saturated state of the contact area of the locomotive wheels with the rails.

41. Analysis of the underframe of the TEM23 diesel locomotive and suggestions for shortcomings elimination.

Author

Abstract

The analysis of the design features of the trolley of the shunting diesel locomotive TEM23. In the process of this analysis the directions for its improvement are determined. It is proposed to ensure the rotation of the trolley frame in the vertical plane by reducing the body supports to two and to use a low-lowered kingpin, to equip the trolleys with pneumatic spring suspension in the form of two-corrugated shells installed in series with shortened spring suspension springs. The proposed options for improving the diesel locomotive undercarriage will increase the competitiveness of products and reduce costs. [ABSTRACT FROM AUTHOR]

Abstract

The problem of the possibility of creating a classification of methods for fastening traction electric motors of railway locomotives to the frame of the trolley is considered. As a result of the analysis, a classification that makes it possible to systematize the design of suspensions of traction electric motors for all known types of drives, as well as suspensions of axial gears is proposed.

47. IR-Emitting Luminescence Properties of CaNb2O6:Yb, Er, Ho.

Author

Moskvitina, E. A. and Vorobiev, V. A.

Abstract

CaNb2O6:Yb, Er, Ho phosphors are prepared by a solid-state reaction. The optical properties, X‑ray diffraction (XRD) patterns, and luminescence mechanism of the phosphors are discussed. The samples are found to be single phases. The CaNb2O6:Yb, Er, Ho phosphor has IR emission under 940-nm excitation. Its IR luminescence spectrum consists of four bands with maxima at 1010, 1200, 1540, and 2070 nm. Energy transfer between activators is observed and analyzed via luminescence properties. The optimal concentrations of CaNb2O6:xYb, yEr, zHo phosphor at which the maximum luminescence intensity is achieved in the region of 2 μm are x = 15 mol %, y = 7 mol %, and z = 1 mol %.
