Fluid-filled pipelines occur in a wide variety of installations where they are excited by sources such as pumps and compressors through both the structure of the pipe wall and the fluid in the system. These vibrations may propagate downstream and result in unwanted radiated noise from the pipeline or connected structures. Although passive measures are available to control both structure and flu...

A methodology for measuring the vibration energy absorbed into the fingers and the palm exposed to vibration is proposed to study the distribution of the vibration energy absorption (VEA) in the fingers-hand-arm system and to explore its potential association with vibration-induced white finger (VWF). The study involved 12 adult male subjects, constant-velocity sinusoidal excitations at 10 diff...

The transverse flow-induced vibration (FIV) of an elastically-supported cylinder-plate assembly (viz., a rigid splitter-plate attached to the downstream side circular cylinder) with low mass ratio 10 and zero structural damping is investigated using numerical simulations at Reynolds number 100. oscillations characteristics flow around structure are analyzed in terms fluid forces as function pla...

Floor vibrations induced by human walking were investigated in a reinforced concrete structure. Six experimental floor structures were built in laboratories with the same dimensions and boundary conditions. Subjective tests were performed to assess the vibration serviceability of the floor structures. First, the subjects were asked to walk across a floor and then to rate the intensity of the vi...

Vibration is an excitatory stimulus for both vestibular and proprioceptive afferents. Vibration applied either to the skull or to the neck muscles of subjects after unilateral vestibular deafferentation induces nystagmus and a shift of the subjective visual horizontal. Previous studies have ascribed these effects to vibratory stimulation of neck muscle proprioceptors. Using scleral search coils...
