Study on the Length of the Effective Vibration Area of the Catenary in a Pantograph–Catenary Interaction System

Applied Sciences
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-loop simulation.

Simulation modeling of the Adjustable Buoyancy Device for open ocean low trophic aquaculture, part I: Test of a submersible long tube unit

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Open‐water low‐trophic aquaculture (LTA) is a sustainable method for producing ocean‐based food and providing ecosystem services. An effective system design is critical for mitigating risks posed by deep ocean forces. Developing submersible cultivation technology requires quantitative risk analysis and modeling to address offshore challenges ...

Multi-parameter optimizations of elastic chain catenary based on response surface methodology for high-speed railway

Frontiers in Mechanical Engineering
As train operating speeds increase, the quality of pantograph-catenary current collection deteriorates, sometimes even resulting in contact loss. To ensure stable current collection during high-speed operation, it is crucial to optimize the design ...

Research on the Influence of Straddle-Type Monorail’s Pantograph Head Parameter on Power Collection Quality

Urban Rail Transit, 2017
At present, the coupling relationship between the pantograph and catenary is not ideal for straddle-type monorail. The power collection quality is poor, and the wear of the contact strip of a pantograph is uneven.
