Rolling system design using evolutionary sequential process optimisation [PDF]

open access: yes, 2008
The design of a rolling system is a multistage process optimization problem involving sequential relationship between consecutive stages. This relationship is peculiar to sequential processes in which the output stock of one stage serves as the input ...

Rolling contact fatigue of silicon nitride. [PDF]

open access: yes
Silicon Nitride has traditionally been used as rolling contact bearing material owing to its superior performance compared to bearing steels. Its successful application as a bearing element has led to the development of Silicon Nitride in other rolling ...

Investigation of resonant phenomena in a locomotive wheelset on the basis of calculation of natural frequencies and modes of their oscillations on finite element models

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2017
From the practice of engineering design it is known that in the development of mechanical systems, the operation of which is certainly not based on the phenomena of resonance, self-synchronization, etc., one should be wary of the proximity of the ...

Influence of the axial loads of rolling stock on the contact-fatigue life of rails

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2018
Analysis of operational data for defective and highly defective rails showed that up to 25 % is the contact-fatigue defects. In connection with the development of heavy haul traffic on the Russian railways, it is relevant to determine the influence of ...

Contact Pressure Measurement System in Cross Wedge Rolling [PDF]

open access: yes, 2010
In the cross wedge rolling process (CWR), plastic deformation is geared by a driving torque transmitted by friction on die surface. Friction plays a role which has to be further identified in this metal forming process. The local contact pressure between

Stator ITSC Fault Diagnosis for EMU Induction Traction Motor Based on Goertzel Algorithm and Random Forest

open access: yesEnergies, 2023
The stator winding insulation system is the most critical and weakest part of the EMU’s (electric multiple unit’s) traction motor. The effective diagnosis for stator ITSC (inter-turn short-circuit) faults can prevent a fault from expanding into phase-to ...

Lubrication of rail by traction unit in the train

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2017
Interaction of rolling stock and track is a fundamental physical process while running cars, locomotives and trains on the railway. The Research, Design and Technological Institute of the rolling stock (JSC "VNIKTI") for more than twenty years conducting

A Locating Approach for Small-Sized Components of Railway Catenary Based on Improved YOLO With Asymmetrically Effective Decoupled Head

open access: yesIEEE Access, 2023
In the routine inspection process of railway catenary systems, the primary task is to find out the locations of various components accurately. The complex composition of the components in the catenary system and their large dimensional differences make ...
