Wrought Mg AZ31 alloy was near-net-shaped by semisolid rheo-diecasting.Parts with 42% and 61% solid fraction were produced at different injection velocities.The impact of injection velocity on the microstructure and the tensile strength of samples have been investigated.Results indicated that the shape factor and the particle size of primary &alpha
Addressing the limitation of existing object detection methods in accurately distinguishing the hazard level posed by foreign objects on railway tracks, this study proposes an intrusion warning approach for foreign object detection and risk assessment on railway surfaces.This method integrates MobileNetv3 with Transformer to detect foreign objects
To address the problems of difficult leveling and poor stability of hill crawler tractors, an attitude adjustment device based on a parallel four-bar mechanism was designed, and the mechanical reasons for the sideslip instability of hill crawler tractors were analyzed.On this basis, a posture adjustment mechanism based on a parallel four-bar mechan
