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 …

Overhead conductor rail (OCR) is an important power supply device in tunnel railway lines.
The penalty method is widely adopted to model the dynamic interaction behaviour of the …

In this paper, The combination of back-propagation neural network (BPNN) and genetic
algorithm (GA) is used to optimize the current collection quality of the pantograph-catenary …

Smooth pantograph-catenary contact is essential for regular train operation. However,
catenary section overlaps are locations where peak contact forces occur, which significantly …

This paper examines the dynamic performance of the pantograph passing through an
overlap section of the catenary system, using a China's high speed railway with the 4-span …

In recent years, the patient specific medical scenario has gained increasing popularity in
health and engineering research. Unlike the standard medical paradigm (generalized …

Bridge hangers, such as those in suspension and cable-stayed bridges, suffer from
cumulative fatigue damage caused by dynamic loads (eg, cyclic traffic and wind loads) in …

In this paper, we propose a general approach to compute the dynamic response of periodic
infinite structures subjected to a moving load. The method only considers one repetitive …

The railway catenary is the typical tensioned beam structure arranged along the railway
lines, supplying power to the moving high-speed trains. The accurate static form-finding and …

Railway overhead contact lines are very low-damped structures with a high modal density in
the low-frequency region. This has a significant impact on the interaction with the …
