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.

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 ...

Analysis of measurement information on steady-state vibrations

Measurement Techniques, 2000
Nowadays practically all forms of machine, including aircraft, are saturated with all kinds of electronic equipment. The equipment performs not only a service function but is the “brain” which is responsible for the efficiency of the machine. The present article is devoted, to analyzing information concerning steady-state vibrations.

Steady state vibrations of framed structures

2011
This thesis is concerned with the determination of Internal Stress Resultants produced in different structural elements of framed structures due to harmonic disturbances. The analysis of frames under vibrating loads has so far been dealt with with physical lumping of the structural mass at the node points where the stiffness influence coefficients are ...

Optimization of Steady-State Vibration Response

2009
This paper is concerned with the optimization of steady-state vibration response of the mechanical system modeled by linear time-invariant second-order system. After rewriting the system as a first-order generalized state-space system (descriptor system), and under the assumptions of regularity, stability and absence of impulsive behavior, the ...

Steady-State Vibrations of a Beam on a Pasternak Foundation for Moving Loads

Journal of Applied Mechanics, 1980
The response of an infinite beam supported by a Pasternak-type foundation and subjected to a moving load is investigated. It is assumed that the load is uniformly distributed over the finite length on a beam and moves with constant velocity. The equations of motion based on the two-dimensional elastic theory are applied to a beam.

Effects of whole body vibration on postural steadiness in an older population

Journal of Science and Medicine in Sport, 2009
The aim of this study was to investigate the effects of vibration exercise on postural steadiness performance in a healthy, older population. Forty-three healthy, older participants (23 men and 20 women, aged 73.5+/-4.5 yr) were randomly assigned to either a vibration group (VIB), an exercise without vibration group (EX) or a control group (CONT).

Steady-state vibrations of a thin two-layer plate with delamination

Journal of Mathematical Sciences, 2000
The authors investigate an infinite two-layer plate with a crack in the upper plate (surface) or in the plate interface. The solution of the problem on harmonic oscillations is found by the method of zero field (see \textit{R. H. T.~Bates} and \textit{D. S. H.~Wall} [Phil. Trans. R. Soc. Lond. A 287, No.~1339, 45--114 (1977)]).

Steady-state vibration of DFT locomotive cabs.

2001
Back injuries and other illnesses for Tranz Rails Locomotive Engineers, is claimed to be attributed to vibration of locomotive cabs. The purpose of this research was to conduct a study in order to determine the complex motion of a DFT locomotive cab and to objectively and quantifiably measure the vibration present in the locomotive.
