Research on the Characteristics of Gas Cushioning Hydraulic Leg Under Impact Condition

Shock and Vibration
Traditional hydraulic legs ensure the safety of the leg through safety valves. However, due to the slow response speed of the safety valve, the safety valve does not respond in time when the hydraulic leg receives an impact, resulting in deformation or ...

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.
