The overlap section is a railway catenary arrangement where the pantograph transfers from
one section to another. In the overlap section, the unsynchronised vibration of two contact …

The interaction performance of the pantograph-catenary is of great importance as it directly
determines the current collection quality and operational safety of trains. The finite element …

For electrified railways, the catenary dynamic behavior is critical to ensure a robust and
steady current collection quality for electric trains. The current collection is achieved as the …

Measuring the pantograph–catenary interaction force is crucial for homologation and
maintenance purposes. However, this is an intricate procedure that requires a specially …

This paper presents a non-contact measurement of the realistic catenary geometry deviation
in the Norwegian railway network through a laser rangefinder. The random geometry …

The numerical tools are widely used to facilitate the design of the railway catenary. Only
radical results are obtained as the current assessment is generally performed without any …

Catenaries are large cable structures which transmit electric current to trains through sliding
contact with a pantograph. The finite element method is widely used to model this dynamic …

The dynamic performance of a high-speed railway vehicle operating in low-temperature
environments was studied through simulations using a stochastic, parameter-based …

Catenary–pantograph contact force is generally used for assessment of the current
collection quality. A good current collection quality not only increases catenary lifetime but …

The fatigue life of coil springs is usually predicted with a stationary Gaussian vibration load
and deterministic structural parameters. However, the obtained fatigue life is inconsistent …
