Research on Influence of Rigid Catenary Locator Offset on Current Collection Performance of Rail Transit Pantograph-Catenary System

Chengshi guidao jiaotong yanjiu
ObjectiveThe rigid catenary serves as a key power supply component for urban rail transit and mountain railway trains. Sliding contact current collection between the rigid catenary and pantograph is critical to the stable and safe operation of ...

Active Control Method for Pantograph-Catenary System Based on Neural Network PID Under Crosswind Conditions

Machines
Crosswind is a critical environmental factor affecting the dynamic interaction between the pantograph and catenary in high-speed trains, which can severely compromise the operational stability of the system. To address this challenge, this study develops

Study on the Length of the Effective Vibration Area of the Catenary in a Pantograph–Catenary Interaction System

Applied Sciences
The effective vibration area includes most of the catenary vibration caused by pantograph–catenary interactions and is the basis of the real-time catenary model for hardware-in-the-loop simulation.

Research on the Mechanical Mechanism and Detection Technology of Abnormal Wear and Contact Wire Disengagement in Rigid Overhead Contact Systems

Machines
The disengagement of contact wires in rigid overhead contact systems (ROCS) is a critical hazard to urban rail transit, potentially causing pantograph–catenary collisions, wire breakage, and large-scale catenary failures.

Feedforward and feedback active control of metro pantographs under abnormal excitations due to track conditions

机车电传动
Metros are predominantly equipped with low-elasticity overhead rigid catenaries, which can easily lead to poor pantograph-catenary relationship. In recent years, abnormal wear has occurred frequently between the pantographs and catenaries in metro ...
