Instability mechanism of deep mine hoisting rope subjected to multi-directional disturbances [PDF]

AIP Advances
The ultra-deep mine hoisting system, operating under high speed and heavy load, is prone to severe vibration instability due to various external disturbances. However, existing studies have mainly focused on single-direction or single-source excitations,

Dual‐Frequency Piezoelectric Vibration Energy Harvester for IoT‐Based Real‐Time Freight Train Health Monitoring in Mongolia

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study evaluates the potential of piezoelectric vibration energy harvesting to power IoT nodes for real‐time health monitoring of the Mongolian railway. Triaxial vibration data were collected at 500 Hz over a 400 km freight route under loaded and unloaded conditions using a custom ESP32‐S3 + MPU9250 system, and dominant frequencies were extracted ...

An experimental study of a circular cylinder's two-degree-of-freedom motion induced by vortex

International Journal of Naval Architecture and Ocean Engineering, 2016
This paper presents results of an experimental investigation of vortex-induced vibration (VIV) of a flexibly mounted and rigid cylinder with two-degrees-of-freedom with respect to varying ratio of in-line natural frequency to cross-flow natural frequency,

A Bayesian Inference Based Operator Skill Evaluation Method for Reliable and Efficient Maintenance of Railway Traction Power Supply Systems

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
A method to quantify the skills of TPSS maintenance operators is proposed by employing the fuzzy comprehensive evaluation method. The operator skills are updated using the Bayesian method with observed behaviours of operators during actual maintenance work.

Algorithmic Energy Management in Constrained Railway Traction Networks: A Systematic Review

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This systematic review synthesises the literature on algorithmic energy management for grid‐constrained multi‐train AC railway networks, classifying the reviewed studies by algorithm family, operational scope and constraint coupling. It finds that single‐train trajectory optimisation cannot represent the coupled electrical interactions that ...

Geometric Prior‐Guided Multi‐Scale Transformer for Long‐Distance Visual Depth Estimation in Power Transmission Channels

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
To address these challenges, this paper proposes a novel geometric prior‐guided multi‐scale transformer for long‐distance visual depth estimation in PTCs. The method innovatively integrates PTC‐specific geometric priors (tower linearity, wire parallelism and terrain smoothness) into a transformer‐based depth estimation framework, and designs a multi ...

Research on the Mechanical Mechanism and Detection Technology of Abnormal Wear and Contact Wire Disengagement in Rigid Overhead Contact Systems

Machines
The disengagement of contact wires in rigid overhead contact systems (ROCS) is a critical hazard to urban rail transit, potentially causing pantograph–catenary collisions, wire breakage, and large-scale catenary failures.
