Lateral girder displacement effect on the safety and comfortability of the high-speed rail train operation

Vehicle System Dynamics, 2021
Rail irregularity presents a major threat to the high-speed train (HST) safety on a high-speed rail (HSR) bridge. Lateral bridge deformation has a significant impact on geometric parameters of the rail.

Temperature field and material response as a function of rail grinding parameters

, 2021
Rail grinding is widely used as a technique to both reprofile the railhead in case of wear and to remove damage. However, grinding may lead to surface burning and the formation of a white etching layer (WEL).

Load quantification of the wheel–rail interface of rail vehicles for the infrastructure of light rail, heavy rail, and commuter rail transit

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017
The type and magnitude of loads that pass through the track superstructure have a great impact on both the design and the performance of the concrete crossties and fastening systems. To date, the majority of North American research that focus on quantifying the rail infrastructure loading conditions has been conducted on heavy-haul freight railroads ...

A rail-to-rail ping-pong op-amp

IEEE Journal of Solid-State Circuits, 1996
A rail-to-rail ping-pong op-amp achieves offset cancellation and 1/f noise reduction without folding of the input spectrum. The clocking scheme minimizes the clock feedthrough and the residual offset due to charge injection. With a clock frequency of 100 kHz, the residual offset is less than 100 /spl mu/V, and the input referred noise is about 225 nV ...

Investigation of the generation mechanism of rail corrugation based on friction induced torsional vibration

, 2021
Field measurements of Wuhan Metro Line 2 show that rail corrugation mostly occurs on the inner rail of curved tracks, and that the corrugation amplitude increases with the curvature of rail.

A 30 V rail-to-rail operational amplifier

Microelectronics Journal, 2015
This work presents a high-voltage (HV) operational amplifier (OPA). OPAs are widely used in signal conditioning circuits for industrial applications and integrated circuits (ICs). Particularly, in HV applications like BMS (battery management system), the signal conditioning circuits are always used to transfer voltage signal between HV domain and low ...

Defect detection method for rail surface based on line-structured light

, 2020
Based on intensive study on rail surface defect, a rail surface defect inspection scheme is proposed in this paper. With high-precession structured laser sensors, the original data are collected by industrial control computer and transformed into ...

Optical Rails

2008
We present a view-based method for steering a robot in a network of positions; this includes navigation along a prerecorded path, but also allows for arbitrary movement of the robot between adjacent positions in the network. The approach uses an upward-looking omnidirectional camera; even a very modest quality of the optical system is sufficient, since

Does growth follow the rail? The potential impact of high-speed rail on the economic geography of China

Transportation Research Part A: Policy and Practice, 2018
The rapidly expanding high-speed rail (HSR) network in China has produced and will continue to produce a progressive contraction of space by significantly shortening the rail travel time among major Chinese cities.
