Free-Free Vibration Extraction From Available Vibration Data

Recent Advances in Solids and Structures, 2000
Abstract This paper presents a procedure for identifying the free-free vibration data of a structure from the available vibration data of the same structure with boundary conditions. For a structure in a mechanical system, depending upon the dynamic formulation used, we may need a set of free-free modal data or a set of constrained modal

Vibrations of Free Rectangular Plates

Proceedings of the Physical Society. Section B, 1949
Records theta are given of the normal vibrating modes and frequencies of free rectangular plates between the limiting shapes of the bar and the square. The nodal systems, which in general consist of straight lines parallel to the sides, are, from considerations of symmetry, divided into four classes.

Free Vibration of Skewed Bridges

Journal of Vibration and Control, 2001
Determination of period of vibration is an essential step in understanding the seismic behavior of bridges. In this paper, an analytical solution for the free vibration problem of slab-beam, single-span skewed bridges is derived. It is assumed that the deck acts as a rigid diaphragm, but the effects of cross-frame and elastomeric bearing stiffnesses ...

Free Vibration of Flexible Cables

Volume 8: 27th Conference on Mechanical Vibration and Noise, 2015
The free undamped vibrations of cables undergoing stretching, bending and twisting are investigated. To this end, a geometrically exact model of elastic cables accounting for bending and torsional stiffness is employed. The cable kinematics retain the full geometric nonlinearities.

Free vibrations ofn-dimensional balls

Acta Mathematica Sinica, 1985
We consider the existence of non-trivial solutions of the problem: \[ u_{tt}-\Delta u+g(u)=0,\quad u_{tt}-\Delta u-g(u)=0,\quad (x,t)\in B\times R \] under the boundary and periodicity conditions: \[ u|_{\partial B^ n}=0,\quad u(x,t+T)=u(x,t), \] where \(B^ n\) is an n-dimensional ball centered at the origin with diameter \(D,T=(b/a)D\); a,b are ...

Transverse Vibration of Free-Free Beams

The Journal of the Acoustical Society of America, 1963
Expressions are derived for the input impedance of damped free-free beams vibrating in their transverse modes, and for the transmissibility of one- and two-stage systems comprised of such beams and lumped elements of mass and compliance. The effect upon transmissibility and input impedance of varying the beam damping is considered in detail.
