Pantograph/Catenary Contact Force Control
Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015In this paper, a new continuum-based pantograph/catenary model based on the absolute nodal coordinate formulation (ANCF) is proposed and used to develop an effective method to control the contact force which arises from the pantograph/catenary interaction.

According to field measurements, the damping ratio of a railway catenary varies along the span length and shows an inherent uncertainty. In numerical simulations, it is common to assume a constant damping ratio. Herein, a methodology is proposed to include the variable damping ratio of a catenary in numerical simulations of pantograph-catenary ...

In this article, the static stresses in a catenary and its vibration modes are calculated by establishing the FEM model of the catenary with Euler–Bernoulli beam elements. The mode shapes of the catenary obtained are considered as the generalized variables which are used in the establishment of the motion equations of the catenary system.

Pantograph-catenary contact force provides the main basis for evaluation of current quality collection; however, the pantograph-catenary contact force is largely affected by the catenary irregularities. To analyze the correlated relationship between catenary irregularities and pantograph-catenary contact force, a method based on nonlinear auto ...

Variation in predicting pantograph–catenary interaction contact forces, numerical simulations and field measurements [PDF]
Vehicle System Dynamics, 2017 ABSTRACTThe contact force between the pantograph and the contact wire ensures energy transfer between the two. Too small of a force leads to arching and unstable energy transfer, while too large of a force leads to unnecessary wear on both parts. Thus, obtaining the correct contact force is important for both field measurements and estimates using ...
