Localized heating and repeated thermal cycling during thick-plate multi-pass welding can produce a complex residual stress state, which may impair the structural reliability of welded components used in marine engines. This study investigates a 55 mm-thick Q235 steel butt joint with a K-groove deposited in 12 passes. B...

With the trend toward higher boosting and lightweight design of diesel engines, the issue of vibration-induced failure of typical structural components has become increasingly prominent. Rapid and accurate prediction of overall engine vibration severity is key to evaluating and improving diesel engine reliability. To a...

Offshore wind turbine blade repair requires stable material removal and precise force regulation under curved‐surface contact and environmental disturbance. To address these challenges, this paper proposes an integrated constant‐force grinding method that combines a passive compliant end‐effector, a particle swarm op...
