In the traditional study and analysis of coupled vibration of pantograph and catenary, pantograph is generally approximated as linear, and most of the linear parameters are obtained by experimental measurement or derivation. In this paper, the flexibility of pantograph head is added into the quality reduction model of pantograph to establish a two-dimension nonlinear pantograph model which will be more suitable for engineering practice. On the premise of that parts of pantograph system are unknown, the non-parametric identification of two-degree of freedom pantograph is carried out by using the restoring force surface method. The identified parameters are basically consistent with the original model data, which indicates that the recognition effect of this method can be accepted. This method has the potential of engineering application, which can promote the in-depth study of pantograph contact stability and make train operation more safe and reliable.
