Effect of vibration exposure duration on discomfort [PDF]
, 2008 The comfort of a seated person exposed to vibration is known to depend on the magnitude, frequency content, and direction of the excitation. A review of the literature showed that very little is known about the effects of the duration of exposure to ...

Ground vibration measurements with special reference to pile driving [PDF]
, 1990 There has been increased concern in recent years over the level and nature of the ground vibrations. The importance of such vibration has increased rapidly due to developments in construction in urban areas, where the effects of ground borne vibration on

Assessment of railway vibrations using an efficient scoping model [PDF]
, 2014 Vibration assessments are required for new railroad lines to determine the effect of vibrations on local communities. Low accuracy assessments can significantly increase future project costs in the form of further detailed assessment or unexpected ...

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Estimation of railway vehicle speed using ground vibration measurements [PDF]
, 2014 In railway noise and vibration assessment, the vehicle speed is a significant concern, since vehicle/track and track/soil interaction strongly affects the vibration magnitude.

Numerical investigation on train-induced environmental vibration in floating ladder tracks [PDF]
, 2020 A floating ladder track is established in the present paper as a next-generation non-ballasted track system. The three-dimensional model consists of a track (mass-spring-damping system) and the underlying soil. Rectangular pulse loading with an amplitude
