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 ...

On Steady-State Harmonic Vibrations of Nonlinear Systems With Many Degrees of Freedom

Journal of Applied Mechanics, Transactions ASME, 1966
A nonlinear spring-mass system with many degrees of freedom, and subjected to periodic exciting forces, is examined. The class of admissible systems and forcing functions is defined, and a geometrical method is described for deducing the steady-state ...

Steady torsional vibrations of a multilayered orthotropic shaft

International Applied Mechanics, 1993
An approximate method was presented for studying the stress state of bodies subjected to cyclic loads. Here, we present the solution to a problem concerning the steady torsional vibration of compound shafts in which the different layers are made of cyclically orthotropic materials.

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 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.
