Abstract

This work uses a periodic catenary model to perform accurate HIL pantograph tests at different train speeds.The catenary representative span is discretized by the Finite Element Method, and the non-linear behavior of dropper slackening is considered.With the catenary model used in this work, the catenary response can be computed in advance so that test delays are easily dealt with.The contact force obtained in the HIL tests for different vehicle speeds is compared with finite element simulations using a linear lumped mass pantograph model.
