Calculation of Free and Forced Lateral Vibrations of a Shaft Line Using Solution Coefficient Vectors [PDF]

TransNav
In this paper, the free and forced lateral vibrations of a marine propulsion shafting system on anisotropic supports are computed using the vectors of solution coefficients method. The transverse vibrations are considered in two orthogonal planes.

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.

On the Countering of Free Vibrations by Forcing: Part II—Damped Oscillations and Decaying Forcing

Applied Mechanics, 2023
The present two-part paper concerns the active vibration suppression for the simplest damped continuous system, namely the transverse oscillations of an elastic string, with constant tension and mass density per unit length and friction force proportional to the velocity, described by the telegraph or wave-diffusion equation, in two complementary parts.

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 ...

SOUND SYNTHESIS OF GONGS OBTAINED FROM NONLINEAR THIN PLATES VIBRATIONS: COMPARISON BETWEEN A MODAL APPROACH AND A FINITE DIFFERENCE SCHEME [PDF]

, 2013
The sound of a gong is simulated through the vibrationsof thin elastic plates. The dynamical equations are necessarily nonlinear, crashing and shimmering being typicalnonlinear effects. In this work two methods are used tosimulate the nonlinear plates: a

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Weight Effects on Vertical Transverse Vibration of a Beam with a Nonlinear Energy Sink

Applied Sciences
Reductions in the vibration of a continuum system via a nonlinear energy sink have been widely investigated. It is usually assumed that weight effects can be ignored if the vibration is measured from the static equilibrium configuration.

The free and forced vibrations of a suspended magnet: Concluded [PDF]

Terrestrial Magnetism and Atmospheric Electricity, 1914
Vertical Disturbance. In 1860 Melde1 showed that a stretched string could be set in strong transverse vibration by a longitudinal movement of its end with a period half that of the transverse vibration. Lord Rayleigh2 pointed out that this principle applied to many kinds of vibrations, and especially that a pendulum could be made to vibrate through a ...
