Recent years saw tremendous developments of data-driven modeling in various
engineering fields. As for the contact modeling between complex surfaces, the utilization of …

In high-speed rail operations, the pantograph-catenary system is commonly utilised to
transmit electricity to the high-speed train. This is achieved through a sliding contact …

The smooth interaction between the pantograph and the catenary is crucial for the
operational safety of railway vehicles. Coupled dynamic models of the pantograph–catenary …

The formation and development of wheel polygon wear (WPW) present significant
challenges to the safety of railway vehicle operations. It is widely accepted that WPW occurs …

This study focuses on developing a comprehensive model of a rigid overhead system, which
includes essential components such as the suspension structure, positioning clamp, and …

Overhead conductor rail (OCR) serves as a crucial device employed in tunnels to power
electric locomotives. The OCR is hung by supports mounted on the tunnel ceiling …

To address existing methodological limitations, a novel method for constructing a simulation
surrogate model for a spiral shaft is proposed based on a double-layer progressive …

The effective vibration area includes most of the catenary vibration caused by pantograph–
catenary interactions and is the basis of the real-time catenary model for hardware-in-the …

Computer-aided simulations are routinely used to predict a prototype's performance. High-
fidelity physics-based simulators might be computationally expensive for design and …

In recent years, structural failures of the pantographs have occurred frequently, posing a
significant threat to the normal operation of pantograph and catenary system (PCS) …
