Web12 de abr. de 2024 · Impulse tightening tools can generate high-frequency vibrations that are not taken into account in currently applicable standards. In various publications, it has been suggested that those high-frequency vibrations may cause health issues. In the present study, high-frequency vibrations produced by an impulse nutrunner are … WebA seismic response analysis with respect to a high-rise building approximately 100 m high is reported. Proper adjustment of the damping coefficient of the HiDAM (oil damper) provided an over all damping factor of about 10–20 per cent to the building structure, and reductions in the response, deformation and shear forces were verified analytically.
Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing … Ver mais Depending on the amount of damping present, a system exhibits different oscillatory behaviors and speeds. • Where the spring–mass system is completely lossless, the mass would oscillate indefinitely, … Ver mais The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly … Ver mais The Q factor, damping ratio ζ, and exponential decay rate α are related such that Ver mais Viscous Drag When an object is falling through the air, the only force opposing its freefall is air resistance.
