Selection of shape for turnout curve of high-speed switches
Transport of the Urals, 2020The main factor at determination of radius of turnout curve under the conditions of comfortable driving is the limitation of centrifugal acceleration increment amount per unit time. For this reason, at designing high-speed switches it is advisable to use variable-radius curves as a turnout curve.

FAULT DIAGNOSIS OF TURNOUT SWITCH MACHINE BASED ON BRAIN-INSPIRED INTELLIGENCE
3rd International Workshop on Structural Health Monitoring for Railway System (IWSHM-RS 2021), 2021As the core equipment to control the running direction of railway vehicle, the turnout switch machine, its failure will lead to a series of problems. At present, more and more researchers conduct intelligent re-search on its fault diagnosis. In this paper, aiming at different types of faults during the operation of turnout switch machines, a spiking ...

A Turnout Switch for a Superconductively Levitated Linear Transport System
IEEE Transactions on Applied Superconductivity, 2007Within the SupraTrans project, a joint venture between research institutes, universities and industrial companies, a full working prototype of a superconductively levitated transport system has been constructed and developed. The levitation and guidance system is based on flux pinning in melt-textured bulk YBa2Cu3O7-delta (YBCO) that stabilizes the ...

Wireless Vibration Monitoring System for Rail Base Defect of Switch Turnout
2017 Far East NDT New Technology & Application Forum (FENDT), 2017Due to asymmetrical structure and motion working state of rail turnout, it is difficult to monitor turnout defect by conventional techniques. In this paper, a wireless vibration monitoring system was proposed for monitoring rail base defect, which could realize two kinds of active and passive working patterns.

Design optimisation of switch rails in railway turnouts
Vehicle System Dynamics, 2013Inspired by a manufacturing process of switch rails for railway turnouts, a method for the optimisation of switch rail profile geometry is presented. The switch rail profile geometry is parameterised with four design variables to define a B-spline curve for the milling tool profile, and two design variables to prescribe the deviation from the nominal ...
