Analysis of Influence Factors of Switching Force and Inadequate Displacement of Switch Rail of NO.9 Turnout

Applied Mechanics and Materials, 2012
Switching force and inadequate displacement are two key issues in the conversion of switch rail, which determined some important parameters such as the traction position of switch machine, the displacement of traction point and the length of switch rail.

Smart Switch: The Application of Fiber Optic Continuous Strain Sensing to the Railroad Turnouts

2022 Joint Rail Conference, 2022
Abstract This paper discusses the application of Fiber Optic-based Continuous Strain Sensing (FOCSS) to Switches (a.k.a. railroad turnouts) and presents the resulting benefits. The FOCSS technology allows effective rail break detection to all parts of the switch and reliable point position detection in a secure environment.

Wheel/Rail Relationship Optimization of Switch Zone in High-Speed Railway Turnout

International Conference on Transportation Engineering 2009, 2009
Wheel/rail relationship design of switch is a core technique in high-speed railway turnout development. A stimulation calculation model is established by employing the train-turnout dynamic theory in order to ensure the stability, safety and switch wear resistance of the turnout on the passenger dedicated lines. Take the 350 km/h PDL NO.

Research on Design of Gauge-Widen Switch for High-Speed Turnout

2012
With the construction of passenger dedicated lines, the demand of high-speed turnouts has been stared in the face. Base on Kinematic Gauge Optimization (KGO), a switch designed by Germany, this paper designs a gauge-widen switch of NO.18 turnout. In order to study the impact of gauge-widen switch on the stability and security of train, the author ...

Numerical simulation of rail profiles evolution in the switch panel of a railway turnout

Wear, 2016
Abstract In order to simulate the rail profiles evolution in the switch panel of a railway turnout, the simulation of vehicle–turnout dynamic interaction, the wheel–rail rolling contact model and rail material wear model are integrated as a numerical simulation tool for rail wear of the switch panel in this paper.

Switch panel design based on simulation of accumulated rail damage in a railway turnout

Wear, 2016
A methodology for numerical prediction of accumulated rail damage in railway turnouts is presented. Based on simulation of dynamic vehicle-track interaction followed by a discretisation of the conditions in each wheel-rail contact, distributions of rail wear are calculated by the Archard model of sliding wear, while surface initiated rolling contact ...

Selecting a Turnout Curve Form in Railroad Switches for High Speeds of Movement

2020
When designing railroad switches for high speeds of movement, it is necessary to provide passengers with a comfortable ride when the train moves on a side track by limiting the values of the so-called centrifugal acceleration and increment (change) of centrifugal acceleration per unit time (second).
