Dynamic Characteristics of Vibrating Flip‐Flow Screens Considering Material Impact Force

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Vibrating flip‐flow screens are widely used in the field of screening; its actual operation is affected by the impact force of materials, but existing research usually ignores this effect. Based on this background, considering the influence of material impact force and moment on vibrating flip‐flow screens, this paper develops a dynamic model ...

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

Robust Control for Uncertain Vertical Electric Stabilization System With Flexible Nonlinearity Using Backstepping Idea

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT A robust control method for the uncertain vertical electric stabilization system (VESS) with flexible nonlinearity is proposed, and the mismatched uncertainty is considered and compensated based on the backstepping idea. First, based on evaluating the coupling effects of the flexible nonlinearity, the analytical dynamics model of the VESS is ...

Study on the Cohesive Characteristic of Nano‐SiO2 Bioinspired Grafting Basalt Fiber and Asphalt

Nano Select, EarlyView.
Nano‐SiO2 bioinspired grafting basalt fiber (BF) was prepared by chemical grafting method based on the bioinspired idea of mussel‐plaque. The mechanism of nano‐SiO2 bioinspired grafting BF was analyzed by micro‐morphology, functional group changes, and elemental composition tests.
