  • hand-arm vibr
  • Clinical aspects of the hand-arm vibration syndrome. (sjweh.fi)
  • At present it seems likely that the different components of the hand-arm vibration syndrome, eg, vibration-induced white finger (VWF), numbing of the hands and arms, muscular fatigue, and occasionally prevalent bone degeneration, may arise independently, and therefore they should be evaluated separately. (sjweh.fi)
  • The lack of simple objective tests for evaluating the hand-arm vibration syndrome makes it difficult to, eg, confirm the history of its different components objectively and estimate the extent of the disability it causes. (sjweh.fi)
  • phone vibration
  • He says detecting a vibrating phone has become a habit, and the slightest muscle twitch or feeling of clothing moving could be wrongly interpreted as phone vibration. (webmd.com)
  • It has been suggested that, when anticipating a phone call, the cerebral cortex may misinterpret other sensory input (such as muscle contractions, pressure from clothing, or music) as a phone vibration or ring tone. (wikipedia.org)
  • Positive Vibration
  • Vincent Ford, a childhood friend from Jamaica, is the songwriter for "No Woman, No Cry" on the 1974 album Natty Dread, as well as the songs "Crazy Baldheads" (with Marley's wife Rita), "Positive Vibration" and "Roots Rock Reggae" from Rastaman Vibration, along with "Inna De Red" and "Jah Bless" with Marley's son, Stephen.

  • There is inherently little damping in a crankshaft to reduce the vibration except for the shearing resistance of oil film in the main and conrod bearings. (wikipedia.org)
  • rotation
  • In general, a molecule with N atoms has 3N - 6 normal modes of vibration, but a linear molecule has 3N - 5 such modes, because rotation about its molecular axis cannot be observed. (wikipedia.org)
  • Because no material can be infinitely stiff, these alternating torques applied at some distance on a shaft cause twisting vibration about the axis of rotation. (wikipedia.org)
  • Lash: Lash in a drive train can cause torsional vibrations if the direction of rotation is changed. (wikipedia.org)
  • analysis
  • It's the first step in creating a meaningful vibration history with more effective vibration analysis practices, more effective planning of maintenance activities and lower maintenance costs. (skf.com)

  • Thus the structural dynamics analysis is a key part of vibration-fatigue evaluation. (wikipedia.org)
  • conclusion showed that the methods by Zhao and Baker, developed in 1992 and by Benasciutti and Tovo, developed in 2004 are also very suitable for vibration-fatigue analysis. (wikipedia.org)
  • The computational effectiveness of vibration-fatigue methods in contrast to the classical approach, enables their use in combination with FEM software packages, to evaluate fatigue after the loading is known and the dynamic analysis has been performed. (wikipedia.org)

  • Below is a list of the most common industrial sectors that employ vibration monitoring. (skf.com)
  • Tail vibration is a common behavior in some snakes where the tail is vibrated rapidly as a defensive response to a potential predator. (wikipedia.org)
  • Random Vibration Testing is one of the more common types of vibration testing services performed by vibration test labs. (wikipedia.org)
  • Some of the more common random vibration test standards are MIL-STD-810, RTCA DO-160, and IEC 60068-2-64. (wikipedia.org)
  • Common sources are: Internal combustion engine: The torsional vibrations of the not continuous combustion and the crank shaft geometry itself cause torsional vibrations Reciprocating compressor: The pistons experience discontinuous forces from the compression. (wikipedia.org)
  • friction
  • Such vibrations could be caused by imbalances in the rotating parts, uneven friction , or the meshing of gear teeth. (wikipedia.org)
  • When the energy of a vibrating system is gradually dissipated by friction and other resistances, the vibrations are said to be damped. (wikipedia.org)
  • Stick slip: During the engagement of a friction element, stick slip situations create torsional vibrations. (wikipedia.org)
  • phenomenon
  • Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point . (wikipedia.org)
  • Some phantom vibration experiences may be a type of pareidolia and can therefore be examined as a psychological phenomenon influenced by individual variances in personality, condition, and context. (wikipedia.org)
  • continuous
  • We conduct continuous monitoring of vibration emissions from construction sites, industrial, rail and transport activities. (sgs.com)
  • different
  • The normal modes of vibration of polyatomic molecules are independent of each other but each normal mode will involve simultaneous vibrations of different parts of the molecule such as different chemical bonds. (wikipedia.org)
  • Tail vibration behavior in rattlesnakes is somewhat different from tail vibration in other snakes because rattlesnakes hold their tails vertically when tail vibrating, whereas other snakes hold the tail horizontally. (wikipedia.org)
  • context
  • For mechanical oscillations in the form of machining context, see Machining vibrations . (wikipedia.org)
