A study on the form of distribution of the experimental value of current collector pressing on the contact wire

Вестник Научно-исследовательского института железнодорожного транспорта, 2016
Current collection, while electric rolling stock is running, is a complex process. The quality of dynamic interaction is estimated at an average contact pressure of current collector and its standard deviation.

Hardware-in-the-Loop Test Bench for Simulation of Catenary–Pantograph Interaction (CPI) with Linear Camera Measurement

Sensors, 2023
Catenary–pantograph contact force is generally used for assessment of the current collection quality. A good current collection quality not only increases catenary lifetime but also keeps a stable electric supply and helps to avoid accidents. Low contact
