Design and testing of a soil-dividing device for a pineapple strip-tillage furrower

To address issues such as high soil backfilling rates and difficulty in maintaining the trench shape during the operation of pineapple strip-rotary cultivators, we designed a V-shaped soil-dividing device. Structural modelling was performed using SolidWorks 2022 by establishing force analysis equations for the soil-div...

High-dimensional multi-objective aerodynamic optimization of a centrifugal air pump through improved impeller–diffuser matching via blade recambering and three-dimensional stacking

This work presents a surrogate-assisted multi-objective aerodynamic optimization of a centrifugal air pump through joint reshaping of the impeller blade and diffuser vane. A 22-dimensional design space is constructed using Bézier-based recambering, leading-edge lean, and independently varied hub and shroud stagger angl...
