Effects of Crosswind on the Aerodynamic Characteristics of High-speed Pantograph
2021 IEEE 24th International Conference on Computer Supported Cooperative Work in Design (CSCWD), 2021Nowadays, electric traction is applied in highspeed trains, and the effects of crosswind increase the instability of the pantograph turbulence, so higher requirements are put forward for the good contact between pantograph and catenary. A new type of pantograph of working height of 2800 mm and a running speed of 400 km/h was taken as the object in this

Active Control of a High-Speed Pantograph
Journal of Dynamic Systems, Measurement, and Control, 1997The design and performance of an active controller for a pantograph which collects current for a high-speed train are considered. A dynamic model of the pantograph/catenary system is described and control objectives are established. A design which incorporates a frame-actuated controller and requires only a single measurement is described.

An Improved Air Spring Model for Pantograph on the High-Speed Train
2022Air spring’s modelling is a relevant subject in the railway field, both for bogie and pantograph suspensions. Considering thermodynamic model has a great advantage for its accuracy and reliability, efforts and huge progress have been made before. However, there are still some parts where efforts could be made: although the air spring’s force and ...

Active Control of Fuzzy for High-Speed Pantograph
Applied Mechanics and Materials, 2012The regular current collection is very important for high-speed train， and can be obviously improved by the use of active control. In order to study the impact of the fuzzy active control on pantograph-catenary system, the model ohe simulation model is created with the software of simulink.

Active Control of a Pantograph Mechanism for High Speed Rail System
2019 IEEE 9th International Conference on System Engineering and Technology (ICSET), 2019The reduction of vibrations in high speed rail system with pantograph mechanism is crucially important to ensure the best riding comfort for passengers. The objective of this study is to stimulate an active control of a pantograph mechanism in high speed rail system. This project presents an approach to increase the performance of high speed rail train

Aerodynamics of trains running inside tunnels change more significantly in comparison with open air scenarios. It has been confirmed that the lateral vibration as well as the aerodynamic drag of the trains is increased and the micro-pressure wave is produced at the tunnel exit when the trains are passing through tunnels.
