Nonlinear Forced Vibrations of Beams

Journal of Applied Mechanics, 1985
An iterative procedure for computing periodic solutions of nonlinear vibrating beams is presented. The nonlinear partial differential equation is replaced by a coupled system of equations. The contraction mapping principle is then applied to generate a method of successive approximations.

Forced lattice vibrations: Part II

Communications on Pure and Applied Mathematics, 1995
AbstractThis is the second part of a two‐part series on forced lattice vibrations in which a semi‐infinite lattice of one‐dimensional particles {xn}n≧1,magnified image is driven from one end by a particle x0. This particle undergoes a given, periodically perturbed, uniform motion x0(t) = 2at + h(yt) where a and γ are constants and h(·) has period 2π ...

Vibrating Needle Cutting Force

Volume 2: Processing, 2014
Needles are one of most commonly used medical devices, used to deliver drugs, biopsy tissue, draw blood, conduct brachytherapy cancer treatment and many other procedures. Maintaining a low insertion force of the needle is important to the success of these procedures. Utilizing vibratory cutting reduces the insertion force, thus improving the outcome of

Vibration type force detector

The Journal of the Acoustical Society of America, 1987
A vibration type force detector in which the vibration string is made of a platinum-based nickel-containing alloy. The magnitude of a force to be detected is obtained through the measurement of a natural vibration frequency of a string vibrating with the force loaded thereto. However, the force detector using a Pt-Ni alloy vibration string based on the

Forced vibration of strings

American Journal of Physics, 1982
The forced vibration of strings has much in common with, on the one hand, their free vibration and, on the other hand, the forced harmonic motion of single objects. But there are also peculiarities, some of which are investigated here. It is found useful to distinguish two kinds of forcing; and some suggestions are made about vibrating strings in such ...

Forced Vibrations of a Nonhomogeneous String

SIAM Journal on Mathematical Analysis, 2008
We prove existence of vibrations of a nonhomogeneous string under a nonlinear time periodic forcing term in the case in which the forcing frequency avoids resonances with the vibration modes of the string (nonresonant case). The proof relies on a Lyapunov–Schmidt reduction and a Nash–Moser iteration scheme.

Vibrating beam force transducer

The Journal of the Acoustical Society of America, 2009
An apparatus and method for monolithic force transducers in which a sensed force is applied across only two ends of a pair of force sensing elements so that the pair of force sensing elements are loaded in series with one in compression and the other in tension, whereby the force sensed by each of the two force sensing elements are identically equal in
