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

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 ...

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.

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.

Analysis and Solutions for Pantograph-Catenary Abnormal Wears
Chengshi guidao jiaotong yanjiu［Objective］ Severe abnormal wear of PC (pantograph-catenary) systems can lead to the breakage of contact wires and the collapse of the overhead network, directly causing power supply interruptions and potentially triggering traffic accidents.
