Modeling and Analysis of Slope-Dependent Response Properties of Gas-Insulated Transmission Line System Under Vehicle-Induced Loads

When a gas-insulated transmission line (GIL) is suspended beneath a bridge with a slope, moving vehicle loads generate both normal and tangential components acting on the supporting system, inducing coupled vibrations among the enclosure, conductors, and insulators. This paper es...

Quasi-zero stiffness TPU interlayer for aluminium–polymer pipe-in-pipe systems: design, modeling and multifunctional performance

An architected thermoplastic polyurethane (TPU) interlayer is proposed for aluminium pipe-in-pipe (PIP) systems to combine load-bearing capacity with vibration attenuation. The interlayer is designed to exhibit a quasi-zero stiffness (QZS) response through geometric deformation....

Continuous-Flow Synthesis of the Key Nicergoline Intermediate 10α-Methoxy-9,10-dihydrolyserol via Photomethoxylation

Abstract At present, the key nicergoline intermediate 10α-methoxy-9,10-dihydrolyserol (3) is predominantly synthesized by photomethoxylation in batch photoreactors, a conventional method plagued by issues such as poor light penetration, low energy efficiency, severe scale-up barr...

Multi-objective optimization of skirt profile for air-cooled pistons based on adaptive ensemble multi-kernel Kriging and an improved hybrid WOA-DE algorithm

Operating under severe thermo-mechanical coupled loads, air-cooled diesel engine pistons are highly susceptible to secondary motion instability, piston slap, and exacerbated friction. To address this multi-objective performance trade-off, this study investigates a representative...

A CPWB-DEMATEL-Based Risk Assessment Method for AR-Assisted Overhead Crane Inspection

Applying augmented reality (AR) glasses to overhead crane inspection can significantly improve the efficiency and accuracy of inspection operations. However, this technology also introduces new and complex risks stemming from the intricate interactions between people, machines, t...

Local Geometric Perception for Climbing Robots on Double-Deck Steel Truss Bridges Using CAD Hole-Layout Priors and Depth-Derived Geometry

Close-range bridge inspection exposes personnel to risks associated with work at height and in confined spaces. Magnetic climbing robots can reduce this exposure, yet dense fastener groups and unsupported regions beyond truss member edges impose local geometric constraints on rob...

A Data-Driven Framework for Planetary Winch Reducer Noise Prediction via Feature Selection and Residual Compensation

Accurate reducer noise prediction is essential for condition monitoring and predictive maintenance of mechanical transmission systems. However, the strong nonlinear coupling between operating conditions and noise responses, together with measurement uncertainties, remains a major...

Temperature‐Dominated Deformation Mechanism and Quantitative Prediction of CF / PEKK Prepreg Tape in LAFP Process

ABSTRACT During laser‐assisted automated fiber placement (LAFP) in situ consolidation, width variations in prepreg tapes lead to gaps or overlaps between adjacent tapes, significantly impairing the forming quality of final components. This study investigates the deformation behav...

Defect Suppression Mechanism of CFRP in Longitudinal-Torsional Coupled Ultrasonic Vibration-Assisted Drilling

Carbon fiber reinforced plastic (CFRP) composites have been widely adopted in the aerospace industry due to their excellent mechanical and physical properties. However, their anisotropy and weak interlaminar bonding make them prone to defects such as delamination and fiber pull-o...

Phase-based self-balancing strategy and performance evaluation of a compact K-H-V planetary vibratory mixer under 43 g high-frequency excitation

To address severe structural vibration and premature fatigue failure in compact high-frequency vibratory mixers, this study proposes an integrated small-teeth-difference planetary vibratory mixer with a phase-based self-balancing mechanism. The mechanism uses a fixed internal rin...
