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...
