摘要

The pantograph was respectively simplified as several different mathematical models, including a lumped mass model, a rigid model, a rigid-flexible hybrid model and a full flexible model. The simulation model of pantograph-catenary system was established and analyzed. The dynamic characteristics were presented, including the contact forces, the accelerations and the corresponding spectra, etc. Subsequently, a comparison of the simulation results of the contact forces with test data was performed. For the different pantograph models, it is proved that there is some difference in the dynamic characteristics, and the rigid-flexible hybrid pantograph model is more reasonable to analyze the dynamic behavior of pantograph and catenary system.
