ICBBA-ACO-Based Multi-Robot Task Allocation for Smart Charging Stations

Smart charging stations require mobile charging robots to respond to dynamically arriving charging requests with heterogeneous priorities, varying travel costs, and uneven workloads while maintaining online scheduling feasibility. Conventional single-layer approaches often optimi...

MFGB-DBSCAN: a multi-factor granular ball-based density clustering algorithm with adaptive parameter optimization

Density-based clustering algorithms such as DBSCAN can identify clusters with arbitrary shapes, but their performance is often limited by global parameter sensitivity and high computational cost on complex datasets. Granular-ball-based methods improve efficiency by replacing poin...

Design method for vibration fatigue suppression of railway freight car body structures and its full-scale vehicle verification

This study investigates the frequent early cracking of sidewall welds in a specific export railway hopper car under mechanized vibration unloading conditions, aiming to reveal the fracture mechanism and propose an effective suppression method. The investigation revealed that the...
