Multi-parameter optimizations of elastic chain catenary based on response surface methodology for high-speed railway

open access: yesFrontiers in Mechanical Engineering
As train operating speeds increase, the quality of pantograph-catenary current collection deteriorates, sometimes even resulting in contact loss. To ensure stable current collection during high-speed operation, it is crucial to optimize the design ...

Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms

open access: yes
Contacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost.
