Intelligent optimized design of novel high‐temperature titanium alloys
Materials Genome Engineering Advances, EarlyView.This paper presents a novel strategy that integrates machine learning with multiobjective optimization to design high‐temperature titanium alloys that simultaneously meet multiple objectives and exhibit superior comprehensive mechanical properties. This approach provides valuable references for the subsequent composition design of high‐temperature ...

NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...
