Optimized winding pattern design for composite pressure vessels using multiobjective particle swarm optimization and mandrel profile updating

To address the winding trajectory deviation and local stress concentration caused by fiber stacking in the dome region of composite pressure vessels, a filament-winding pattern design method based on multiobjective particle swarm optimization (MOPSO) and mandrel profile updating...

Operational risk assessment for spinning frame tenders based on WMSD

Currently, the risk of work-related musculoskeletal disorders (WMSDs) in the textile industry is on the rise annually. Effectively assessing the risk of WMSDs caused by the operational behaviors of spinning frame tenders has become a critical issue demanding urgent resolution in...

Impact of Movement Amplitude in Dynamic Visual Cues on Motor Imagery Ability and BCI Classification

Motor imagery-based brain-computer interface (MI-BCI) is an important research topic in the field of motor function rehabilitation. Although dynamic visual cues can modulate motor imagery (MI) performance, the role of movement amplitude remains underexplored. This study investiga...

Achieving simultaneous strength-ductility-corrosion optimization of solid-state additive friction stir deposited superlight Mg-Li alloy by a hybrid high flow rate Argon/CO₂ shielding atmosphere

High-performance Mg–Li alloys were fabricated via solid-state additive friction stir deposition under a mixed Ar/liquid CO₂ atmosphere, which addresses severe oxidation and unfavorable thermal cycling issues during additive manufacturing. Benefiting from optimized microstructures...
