Research shaped by real operating problems
We study maglev application planning, transport organization, train operation, dispatching, and traction-power coordination, connecting scenario assessment with optimization, algorithms, and system validation.
01
High-speed maglev networks and techno-economic analysis
Functional relations, interfaces, and techno-economic comparisons between high-speed maglev and existing high-speed rail networks.
02
Low-speed maglev freight models and planning assessment
Freight models, transport organization, system capacity, and cost for low-speed permanent-magnet maglev in urban logistics.
03
Train speed profiles and energy-efficient operation
Traction, cruising, coasting, and braking are optimized under line and running-time constraints for safe, punctual, and energy-efficient operation.
04
Transport organization and operational dispatching
Service frequency, station calls, departures, and section running times are coordinated with headway and line-capacity checks.
05
Coordination of organization, train control, and traction power
Timetables, speed trajectories, power capacity, and multi-train load are coordinated across transport, control, and power layers.
