Influence of main operating conditions on contact wire wear of rigid catenary lines [PDF]

A validated overhead conductor rail and a well-known wear model have been programmed to perform closer-to-reality simulations. Reliable wear rate estimates for two configurations of overhead conductor rails and three models of pantographs at different ...

Investigation on Monitoring System for Pantograph and Catenary Based on Condition‐Based Recognition of Pantograph

Shock and Vibration, Volume 2019, Issue 1, 2019., 2019
In recent years, the length of electrified railway systems has increased along with the number of railway vehicles in China. For the pantograph‐catenary system, as one of the key components of the vehicle system, an urgent problem includes diagnosing faults and proposing a safety monitoring system to assure safe operation, improve the level of ...

Wind‐Induced Coupling Vibration Effects of High‐Voltage Transmission Tower‐Line Systems

Shock and Vibration, Volume 2017, Issue 1, 2017., 2017
A three‐dimensional finite element model of a 500 kV high‐voltage transmission tower‐line coupling system is built using ANSYS software and verified with field‐measured data. The dynamic responses of the tower‐line system under different wind speeds and directions are analyzed and compared with the design code.

A Flexible Multibody Pantograph Model for the Analysis of the Catenary–Pantograph Contact

, 2011
The pantograph–catenary system is still the most reliable form of collecting electric energy for running trains. This system should ideally run with relatively low contact forces, in order to minimize wear and damage of the contacting elements but ...

Nonlinear Seismic Behavior of Different Boundary Conditions of Transmission Line Systems under Earthquake Loading

Shock and Vibration, Volume 2016, Issue 1, 2016., 2016
Nonlinear seismic behaviors of different boundary conditions of transmission line system under earthquake loading are investigated in this paper. The transmission lines are modeled by cable element accounting for the nonlinearity of the cable. For the suspension type, three towers and two span lines with spring model (Model 1) and three towers and four

Numerical Algorithms for the Analysis of Initial Configuration in a Railway Catenary Structure and Its Code Implementation: A Software Tool CALPE

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
To obtain the best operating conditions in a railway infrastructure, as the pantograph/catenary system, is a priority issue in modern railways, for a correct management and the best performance of this infrastructure. Although most of the published works on this subject are oriented to solving dynamic problems, in order to successfully address these ...

Seismic Response of Power Transmission Tower‐Line System Subjected to Spatially Varying Ground Motions

Mathematical Problems in Engineering, Volume 2010, Issue 1, 2010., 2010
The behavior of power transmission tower‐line system subjected to spatially varying base excitations is studied in this paper. The transmission towers are modeled by beam elements while the transmission lines are modeled by cable elements that account for the nonlinear geometry of the cables.

Evaluating Different Approaches for Modelling Rotor Aero‐Servo‐Dynamics in Frequency‐Domain Analysis of Floating Wind Turbines

Wind Energy, Volume 28, Issue 11, November 2025.
ABSTRACT Computationally efficient frequency‐domain models can play a very important role in facilitating conceptual design optimization of floating wind turbines (FWTs). However, achieving sufficient accuracy in such models is challenging due to the nonlinear variation of the aerodynamic loads, particularly the interaction between the floating ...

Hardware in the Loop Test‐Rig for Identification and Control Application on High Speed Pantographs

Shock and Vibration, Volume 11, Issue 3-4, Page 445-456, 2004., 2004
Trains current collection for traction motors is obtained by means of a sliding contact between the overhead line (OHL) and the collector strips mounted on the pantograph head. The normal force by which the collector presses against the contact wire ensures the contact pressure for the electrical contact.

Development of scalable coastal and offshore kelp farming for marine biomass production

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract The US DOE/ARPA‐E MARINER program funded a 4‐year project to determine an optimal way to grow kelps in large, nearshore and offshore arrays for the eventual purpose of biofuel production with the goal of keeping the cost below $80 USD per dry metric ton of kelp.
