Effect of the dry friction damping structure on the localized vibration of mistuned bladed disk
Journal of Hebei University of Science and Technology, 2019 In order to study the effect of the dry friction damping structure on the localized vibration of mistuned bladed disk, the forced vibration response of a mistuned bladed disk with dry friction damping structure is investigated by using three-dimension ...

The experimental response of a broadband base-excited vibration isolator incorporating cubic damping
, 2013 Structural damping is often assumed to be viscous and linear which leads to comparatively straightforward vibration analysis. In the case of vibration isolation mounts this assumption of linearity is particularly questionable and one might want to know ...

Nonlocal Metaspire: A Scalable Elastic Material Platform With Decoupled Mechanical Modes
Advanced Materials, EarlyView.Nonlocal Metaspire introduces sequential rotation to realize wider scalability in implementing complex nonlocal couplings in elastic metamaterials while suppressing unintended mode coupling. Numerical results clarify the underlying wave motions, demonstrate mode‐decoupled roton and maxon formation, and support a straightforward extension to higher ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization
Advanced Materials Technologies, EarlyView.An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
