Design of dynamic absorber for two DOF system by fixed points theory (2nd report: case of the system with different mass and stiffness, and excited secondary mass)

Nihon Kikai Gakkai ronbunshu, 2015
The fixed points theory is applied for the dynamic absorber attached to two degree of freedom system with different mass and stiffness. In this study, the case that the dynamic absorber is connected to the excited mass which is far from the base is ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Modeling of magnetic damper composed of ring magnet and coaxially and relatively moving conducting disk considering skin effect

Nihon Kikai Gakkai ronbunshu, 2016
A magnetic damper composed of a permanent magnet and a conducing plate has the advantage that the magnetic damper can generate a damping force with no physically contact.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
