Random dynamic analysis on a high-speed train moving over a long-span cable-stayed bridge
International Journal of Rail transportation, 2021This paper presents random dynamic analysis on a high-speed train moving over a long-span cable-stayed bridge. In the study, the train, slab track, and bridge are regarded as an integrated system, each vehicle is modelled as a four-wheelset mass-spring ...

Static and Dynamic Characteristics of a Long-Span Cable-Stayed Bridge with CFRP Cables [PDF]
Materials, 2014 In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration,

A Modular Multilevel Converter With Filter Capacitor for Long-Cable-Fed Drive Application
IEEE transactions on industry applications, 2019This paper proposes a modular multilevel converter (MMC) with a filter capacitor for medium-voltage long-cable-fed drive applications. Arm inductors that are inherent components in each phase of MMC are tuned with a filter capacitor to behave like a low ...

ON LONG-TERM BEHAVIOR OF CABLES IN CABLE-STAYED BRIDGES
Doboku Gakkai Ronbunshu, 1986The Locked Coil Rope cables of cable-stayed bridges have reportedly undergone significant relaxation and the deflections of the girders have also increased noticeably year after year from a number of field measurements. In this paper, an attempt is made to account for such behavior analytically assuming that the cables follow the linear visco ...

Quasi - two-level converter operation strategy for overvoltage mitigation in long cable applications
International Electric Machines and Drives Conference, 2019This paper focuses on a Quasi-Two-Level (Q2L)converter topology and its use in long cable application, where overvoltage at the motor terminals due to wave reflection threatens the motor and cable insulation.

Long-term cable vibration monitoring and cable tension estimation of a cable-stayed bridge
Materials Research Proceedings, 2023Abstract. This study aims to investigate the applicability of ambient cable vibrations for cable tension estimation and the identification uncertainty and effect of EOVs in the long-term SHM of cable tensions. An advantage of long-term ambient vibration monitoring is that there is no need to close roads for the monitoring campaign once a monitoring ...

Cable force monitoring and prediction for cable group of long-span cable-supported bridges
Journal of Civil Structural Health Monitoring, 2018Cable force monitoring is an essential and critical part of structural health monitoring for long-span cable-supported bridges. Considering economical and efficient issues, the accuracy and quality of safety assessment depend considerably on a reasonable cable-monitoring scheme, especially the number and locations of limited sensors.

A Linear Preamplifier for Driving a Long Coaxial Cable
Review of Scientific Instruments, 1950A circuit for driving a long coaxial cable is described. Its response characteristics permit impedance matching of the coaxial line without sacrificing linearity of response, and make possible a relatively long line between the particle detector and the recording apparatus.
