Calculation of Synchronous Reluctance Machines Used as Traction Drives
2015 IEEE Vehicle Power and Propulsion Conference (VPPC), 2015In this paper, the use of synchronous reluctance machines as traction drives for electric vehicles is investigated. For this purpose, a synchronous reluctance machine is designed. In the first step, the machine is optimized for the rated operating point.

EMFRail: A Tool to Calculate Rail Traction Electromagnetic Fields
2017 Joint Rail Conference, 2017EMC/EMI is a source of concern from the beginning of planning a new railway line. High powered electrified railways such as HSR are usually AC electrified. This poses a hazard for nearby systems and users. Induced voltages can create electric shock risks or malfunction in signalling or other nearby systems.

Digital Protection of Traction Network and Setting Calculation Features
2018 XIV International Scientific-Technical Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2018The reliable operation of DC traction network feeders’ protections is one of the main vehicles problems. The usage of special devices was proposed to solve that problem., but it did not raise the system reliability. Protection devices reacted to one parameter: current., voltage., resistance., heating of current-carrying parts.

Calculation of asynchronous traction motor start-up characteristics by FEM method
International Symposium on Power Electronics Power Electronics, Electrical Drives, Automation and Motion, 20122D and 3D calculation of squirrel-cage traction motor start-up characteristics at rated voltage and frequency have been performed by using a numerical FEM based program. From the equivalent circuit parameters, which are obtained by analytical calculation, a simulation of a start-up using an analytical dynamic model was performed.

New Results of Traction Force Calculations in Elastohydrodynamic Contacts
Journal of Tribology, 1985The lubricant shear modulus G and Ree-Eyring shear stress τ0 are determined in this work by using Roelands’, rather than Barus’, relationship for calculating the lubricant viscosity. When using Roelands’ viscosity, elastic effects in the lubricant tend to be negligible, especially when inlet shear heating and displacement of the center of pressure are ...

Calculation of superconducting traction transformer 1MVA and its cooling
2005 IEEE Russia Power Tech, 2005This paper deals with the Superconducting traction transformer (STT) 1MVA and its cooling. The idea of this usage originated in the SKODA Research Ltd., Pilsen. The paper compares the classical transformer and STT. The second part describes cooling of the STT. This part is complemented by calculations of the heat exchange.

Calculation of the traction effort of ISEAUTO self-driving vehicle
2018 25th International Workshop on Electric Drives: Optimization in Control of Electric Drives (IWED), 2018This paper presents a novel approach to traction effort calculation for a self-driving car. Self-driving cars usually require reliable and accurate path planning algorithms to operate in dynamically changing environment. The first self-driving car project in Estonia started with the cooperation of Tallinn University of Technology and Estonian company ...

Calculation of the work done by deformation-dependent tractions
2015Summary: A generalization of the well-known Nanson's formula for solids has been set up for shells. These formulae relate a surface element vector taken either on the base surface or on the side surface in the reference configuration to any surface element vector in the instantaneous configuration.
