Overhead Line Emulation with PHiL
This experiment is a demonstrator of the moving railway catenary dynamics. The purpose of this experiment is to reproduce the forces created by the contact wire onto the pantograph of a train. Indeed, the contact wire exhibits oscillations, depending on the catenary system geometry (mast, dropper, insulator, etc.) and the train speed.
The first figure shows the arm exerting a force on a current collector (scaled version). The complete set-up can be seen in the second figure. Here the behaviour of the virtual model is illustrated on the screen.
Challenge for the Teaching
- Study the different vibration modes of the contact wire
- Test different catenary and pantograph geometries
- Employ modern control theory to emulate virtual system behaviour
Application in Practice
- Mechatronic impedance control
- Mass spring damper systems
- Bending beam / tensioned string
- Railway catenary design and test
