Pantograph/Catenary Contact Force Control [PDF]
Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015 In 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.

The Effects of Spatially Distributed Damping on the Contact Force in Railway Pantograph-Catenary Interactions [PDF]
IEEE Transactions on Instrumentation and Measurement, 2021 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 ...

Application of new optical load cells for in-line measurement of pantograph-catenary contact force [PDF]
SPIE Proceedings, 2013 The contact force between pantograph and catenary is a parameter needed to evaluate the quality of the dynamic interaction of the two systems. The in-line measurements of this parameter have always been very hard due to the particular work condition of pantograph and catenary.

This paper explores the use of pantograph–catenary contact force (PCCF) for monitoring of the current collection quality and detection of anomalies in the interaction between pantograph and catenary. The concept of catenary structure wavelength (CSW) is proposed as the dominant component of PCCF.
