Sympodial tree-like structures: From small to large-amplitude vibrations.

This study deals with tree-like structures that mimic a trunk with either first-order branches or both first and second-order branches of a sympodial tree. The corresponding mechanical model comprises physical pendula coupled with torsional springs and viscous dampers. Natural frequencies and modal shapes are obtained analytically and the effects of a branching angle and a stiffness ratio on th...

Large Amplitude Vibrations in the HFClF Complex

Os movimentos de grande amplitude no complexo HF...ClF foram estudados teoricamente. Na solução das equações dinâmicas foi utilizada uma superfície de energia potencial ab initio calculada a nível MP2/DZ+(2d1f/2p1d)//HF/DZP, incluindo a correção para o erro de superposição do conjunto de bases (BSSE). A freqüência para o estiramento da ligação de van der Waals e a freqüência e a intensidade da ...

Longitudinal-Torsional and Two Plane Transverse Vibrations of a Composite Timoshenko Rotor

In this paper, two kinds of vibrations are considered for a composite Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic and potential energies and virtual work due to the gyroscopic effects are calculated and the set of six governing equations and boundary conditions are derived using Hamilton principle. Differential quadrature method (DQM) is used as ...

Fringe-free holographic measurements of large-amplitude vibrations.

In the measurement of the amplitude of vibration of objects, holographic imaging techniques usually involve fringe counting; because of the limited resolution of the images, measurements of large amplitudes are not accessible. We demonstrate a technique that suppresses the necessity of fringe counting--frequency sideband imaging--where the order of the sideband is considered a marker of the amp...

Computations for Large Amplitude Two-Dimensional Body Motions

A numerical method is presented for the time-domain simulation of large amplitude motions of a 2-D surface piercing body with arbitrary shape in deep water. Based on potential theory, panels are distributed on the body and desingularized sources are distributed above the calm water surface. The body boundary condition is satisfied on the exact submerged body surface. The free surface boundary c...
