Upgrading Pantograph Performance Using Variable Stiffness Devices

This paper introduces a new technique for improving pantograph current collection performance. The technique involves replacing pan springs with variable stiffness devices. The device described here comprises 2 facing air springs. The paper first gives an outline of the method used for improving current collection performance together with some results from numerical simulations, which demonstrate the technique's effectiveness. Secondly, the paper briefly introduces a prototype of the variable stiffness device, describing its basic characteristics. Finally, results are presented from experiments in controlling dynamic pantograph characteristics using the variable stiffness devices.
