Pantograph

, 2017
Toto téma jsem si vybrala, že je mi blízké strojírenství, kde se pantograf vyskytuje, ale i že mám ráda fyziku z které má pantograf páky. Cílem mojí práce je vyrobit použitelný pantograf pro výuku, dále vyrobitelný v podmínkách školních dílen s běžnými ...

Kinematics of pantograph masts

, 2009
This paper deals with the kinematics of pantograph masts. Pantograph masts have widespread use in space application as deployable structures. They are over constrained mechanisms with degree-of-freedom, evaluated by the Grübler–Kutzback formula, as less ...

Numerical study on pantograph raising and lowering in multi-pantograph operation

Multi-pantograph operation is a convenient and efficient way to operate railway rolling stock, but the influence between the pantographs makes the system more sensitive and vulnerable than a single-pantograph system.

Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms

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.
