Failure Analysis and Structural Optimization for Elastic Element of High-speed Pantograph

机车电传动, 2020
The elastic element of high-speed pantograph is used to relieve the shock and vibration between pantograph and catenary to ensure the dynamic current collection of pantograph head is stable and reliable.

Computational fluid dynamics-multibody system dynamics bidirectional coupling calculation and flow-induced vibration evaluation of a high-speed pantograph-catenary system

Engineering Applications of Computational Fluid Mechanics
Increasing the speed of a pantograph deteriorates its aerodynamic performance and aggravates the problem of flow-induced vibration, which is not conducive to the stability of the pantograph – catenary system (PCS). Currently, commercial high-speed trains

A Reduced Pantograph-Catenary Interaction Model for Efficient Pantograph-Catenary Interaction Dynamic Analysis

The continuous movement of high-speed train results in the pantograph interacting with a long catenary structure. The traditional methods based on the Lagrangian description can only model the whole long catenary structure, which decreases their ...

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

, 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 ...

Unsteady aerodynamic forces on a railway pantograph and their influence on pantograph-catenary dynamic interaction

, 2018
Pantograph and overhead line aerodynamics is responsible for affecting the con-tact force between the pantograph and the contact wire, both in terms of average value and dy-namic variation. Stationary forces acting on pantograph components can change the

Pantograph/Catenary Contact Formulations

, 2017
In this investigation, the pantograph/catenary contact is examined using two different formulations. The first is an elastic contact formulation that allows for the catenary/panhead separation and for the analysis of the effect of the aerodynamic forces,
