Active Control of Contact Force for a Pantograph-Catenary System [PDF]
Shock and Vibration, 2016 The performance of the high speed trains depends critically on the quality of the contact in the pantograph-catenary interaction. Maintaining a constant contact force needs taking special measures and one of the methods is to utilize active control to ...

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

Variation in predicting pantograph–catenary interaction contact forces, numerical simulations and field measurements [PDF]
Vehicle System Dynamics, 2017 ABSTRACTThe contact force between the pantograph and the contact wire ensures energy transfer between the two. Too small of a force leads to arching and unstable energy transfer, while too large of a force leads to unnecessary wear on both parts. Thus, obtaining the correct contact force is important for both field measurements and estimates using ...

Intelligent Contact Force Regulation of Pantograph–Catenary Based on Novel Type-Reduction Technology [PDF]
Electronics (Switzerland), 2022 In this paper, an intelligent control scheme is proposed to suppress vibrations between the pantograph and the catenary by regulating the contact force to a reference value, thereby achieving stable current collection. In order to reduce the computational cost, an interval Type-2 adaptive fuzzy logic control with the Moradi–Zirhohi–Lin type reduction ...

Sliding Mode Control with PD Sliding Surface for High-Speed Railway Pantograph-Catenary Contact Force under Strong Stochastic Wind Field [PDF]
Shock and Vibration, 2017 As is well known, the external disturbance (especially the stochastic wind load) has nonnegligible effect on the operation of pantograph-catenary system, which may cause the strong fluctuation in contact force as well as the increased occurrence of ...

Mechanism and Machine Theory, 2017 Abstract Active control of pantograph is a promising approach in improving the current collection quality of high-speed railway pantograph-catenary system. To address the shortcomings of the lumped-parameter pantograph model used in previous studies, a multi-body model of pantograph is established, and two configurations of installing actuators on a ...
