Effects of Exposure to Localized Vibration on Hand Steadiness

Perceptual and Motor Skills, 1969
32 Ss performed a steadiness task before and again immediately after 3 min. of exposure to localized vibration. The vibratory forces were transmitted to S's performing hand through a specially constructed gripping handle which vibrated at either 60, 80, or 100 cps at a constant amplitude. Each S was exposed to each vibration frequency and also to a no-

MAINTENANCE OF WALKING ROBOT IN STEADY POSITION BY MEANS OF VIBRATION

International Journal of Humanoid Robotics, 2011
A walking robot is considered. For leg lightness, it is suggested in some cases to miniaturize its cross section. At that buckling of the leg rectilinear form is possible under dead weight. To keep the rectilinear form, it is proposed to place a vibroexciter for vertical oscillations in the bottom of the leg.

Steady-state vibrations of offshore structures

Hydrotechnical Construction, 1994
Offshore structures subjected to the action of drifting ice floes may experience several kinds of interactions with the ice feature. This paper addresses the structural response to forces that arise when the ice floe fractures against a vertical structure. Special attention is paid to the steady-state vibrations which may arise at medium ice velocities.

Steady-State Behavior of Nonlinear Dynamic Vibration Absorber

Journal of Applied Mechanics, 1961
The Frahm-type dynamic vibration absorber is analyzed for the case where both main and absorber springs have nonlinearities of the Duffing type. A one-term-approximation solution is assumed for the motions of the two masses, and the resulting amplitude equation is solved using a graphical procedure.

The steady streaming induced by a vibrating cylinder

Journal of Fluid Mechanics, 1975
In this paper we apply the techniques of higher-order boundary-layer theory to study the steady streaming induced in the neighbourhood of a cylinder which vibrates harmonically, perpendicular to its generators, in an unbounded fluid. The theoretical predictions are compared with the results of experiments performed at high streaming Reynolds numbers ...

Plane steady vibration of an orthogonal elastic wedge

Journal of Elasticity, 1974
The problem is reduced to a single Fredholm integral equation by using a superposition of two half-plane solutions. The treatment is exact within the theory of linear elastodynamics. Dissipation is introduced in the form of linear viscous damping at the surface in order to overcome the mathematical difficulties which are associated with the nondecaying

Steady State Vibrations of a Piecewise Linear System

Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract In this paper we examine the dynamics of a mechanical system with a piecewise linear damping and stiffness, which is characterized as a strongly nonlinear system. Searching for the exact steady state periodic response of piecewise linear systems for harmonic excitations, lead to a set of transcendental equations which should be ...

Steady forced vibrations in coupled thermoelasticity

Archive for Rational Mechanics and Analysis, 1986
This fine paper is devoted to the study of the forced longitudinal vibration of a bar excited by a harmonic force within the frame of linear coupled thermoelasticity. The authors shows that, due to thermomechanical coupling, which results in dissipation of mechanical energy, a unique solution exists for any driving frequency.

Steady State Vibration of Damped Timoshenko Beams

Journal of the Structural Division, 1968
A method for the analysis of the steady state vibration of damped Timoshenko beams is presented. The usual four differential equations of the Timoshenko Theory are increased to eight differential equations with the addition of damping in the form of complex modulii.
