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.

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 ...

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 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.

Steady planar vibrations of an isotropic body with cavities

Journal of Mathematical Sciences, 1995
We solve the planar-deformation problem for a multiconnected isotropic body deformed by a pulsing load. For a circular cylinder with a circular central cavity we give the results of numerical studies of the stress distribution and the frequencies of the natural axisymmetric vibrations.
