MR Damper Controlled Vibration Absorber for Enhanced Mitigation of Harmonic Vibrations
This paper describes a semi-active vibration absorber (SVA) concept based on a real-time controlled magnetorheological damper (MR-SVA) for the enhanced mitigation of structural vibrations due to harmonic disturbing forces. The force of the MR damper is controlled in real-time to generate the frequency and damping controls according to the behaviour of the undamped vibration absorber for the act...
متن کاملOffice floor vibrations: modal parameter identification and vibration monitoring
Several people working on the 2nd floor of an office building complained about disturbing floor vibrations. The building consists of five floors. In the contrary to the other floors, the 2nd floor slab has no floor-to-ceiling secondary walls neither beneath nor on top of the slab. The modal parameters of four floors were identified using ambient vibration testing (AVT)-technology and a 5-kg-med...
متن کاملLocalized Vibration-Formation by Driving Raman Active Molecular Vibrations
The study on local modes as a molecule's eigen-vibration is still an attracting topic [1,2]. However, a new trend becomes more popular: people are more interested in the vibration properties of molecules under interactions with external laser fields for practical usages such as bond-selective photodesorption [3, 4] and vibrationally mediated dissociation [ 5 7 ] . We have already studied the po...
متن کاملWhole body vibration exercise: are vibrations good for you?
Whole body vibration has been recently proposed as an exercise intervention because of its potential for increasing force generating capacity in the lower limbs. Its recent popularity is due to the combined effects on the neuromuscular and neuroendocrine systems. Preliminary results seem to recommend vibration exercise as a therapeutic approach for sarcopenia and possibly osteoporosis. This rev...
متن کاملGood Vibrations: A Vibration Damping Setpoint Controller for Continuum Robots
In this paper, we focus on a class of robotic manipulators that utilize continuous backbone structures. Such manipulators, known as “continuum” robots, exhibit behavior similar to tentacles, trunks, and snakes. Specifically, we have previously discussed some of the mechanical and kinematic details of the Clemson “Tentacle Manipulator.” This work examines the dynamic characteristics of this mani...
