The effect of axial loads on free vibration of symmetric frame structures using continuous system method [PDF]

open access: yesJournal of Structural and Construction Engineering, 2016
The free vibration of frame structures has been usually studied in literature without considering the effect of axial loads. In this paper, the continuous system method is employed to investigate this effect on the free flexural and torsional vibration ...

Suppression method for rebound amount of the internal mirror model of an SLR camera

open access: yesMechanical Engineering Journal, 2015
In this study, the rebound vibration characteristics of the internal mirror of an SLR camera are investigated using experimental models. The mechanism of the mirror rebound phenomena is tested by using four types of rectangular metal plate models.

New Damped-Jerk trajectory for vibration reduction [PDF]

open access: yes, 2014
This paper derives a jerk-shaped profile to address the vibration reduction of underdamped flexible dynamics of motion system. The jerk-limited profile is a widespread smooth command pattern used by modern motion systems.

Dynamic characteristics and growth curve of rail corrugation at saturation stage

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Rail corrugation, which causes the vibration and the noise, is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running.

Relation between vibrotactile perception thresholds and reductions in finger blood flow induced by vibration of the hand at frequencies in the range 8–250 Hz [PDF]

open access: yes, 2014
Purpose: this study investigated how the vasoconstriction induced by vibration depends on the frequency of vibration when the vibration magnitude is defined by individual thresholds for perceiving vibration [i.e.

Normal Modes of Vibration for Non-Linear Continuous Systems [PDF]

open access: yesJournal of Sound and Vibration, 1994
A definition and a constructive methodology for normal nodes of motion are developed for a class of vibratory systems the dynamics of which are governed by non-linear partial differential equations. The definition for normal modes is given in terms of the dynamics on two-dimensional invariant manifolds in the system phase space.

Simulation analyses of progress process of rail corrugation

open access: yesNihon Kikai Gakkai ronbunshu, 2019
Rail corrugation is such phenomenon that roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running, and cause the vibration and the noise.
