A Study on Dynamic Behaviour of Pantographs by Using Hybrid Simulation Method

Abstract

To study the dynamic behaviour of pantographs, a hybrid simulation method has been used. A special test facility, which is used to simulate the dynamic performance of a pantograph when it runs through the overhead line, is established and described in this paper. As the catenary is difficult to be modelled by a hardware test facility indoor, a mixed theoretical-experimental technique is used in test facility. On the basis of the set-up of hybrid simulation test device of the pantograph-catenary system, the dynamic behaviours of four types of pantographs running along the overhead equipment at different running speeds are examined and compared. Meanwhile, the dynamic parameters such as mass, stiffness, and damping of four pantographs are measured using the hybrid simulation test facility. On the basis of these parameters, the dynamic behaviours of the four pantographs are analysed.
