Tremor Reduction at the Palm of a Parkinson’s Patient Using Dynamic Vibration Absorber
Parkinson's patients suffer from severe tremor due to an abnormality in their central oscillator. Medications used to decrease involuntary antagonistic muscles contraction can threaten their life. However, mechanical vibration absorbers can be used as an alternative treatment. The objective of this study is to provide a dynamic modeling of the human hand that describes the biodynamic response o...
متن کاملDynamical stability of cantilevered pipe conveying fluid in the presence of linear dynamic vibration absorber
When the velocity of fluid flow in a cantilevered pipe is successively increased, the system may become unstable and flutter instability would occur at a critical flow velocity. This paper is concerned with exploring the dynamical stability of a cantilevered fluid-conveying pipe with an additional linear dynamic vibration absorber (DVA) attachment. It is endeavoured to show that the stability o...
متن کاملAn Overview of Disarray in Vibration Analysis of Undamped Dynamic Vibration Absorber
There are numerous sources of vibration in an industrial environment: in processes such as pile driving and blasting; rotating and reciprocating machinery such as engines, Compressors, and motors; transportation vehicles such as trucks, train and aircraft; the flow of fluids; and many others. Vibration absorption is a method of adding a tuned spring-mass absorber to a system to create anti-reso...
متن کاملNoise reduction by dynamic signal preemphasis.
In this work we propose an approach to reduce the digitization noise for a given dynamic range, i.e., the number of bits, of an analog to digital converter used in an NMR receiver. In this approach, the receiver gain is dynamically increased so that the free induction decay is recorded in such an emphasized way that the decaying signal is digitized using as many number of bits as possible, and ...
متن کاملApplication of an active electromagnetic vibration absorber in vibration suppression
A novel active electromagnetic vibration absorber (AEMVA) is developed. It is shown that for suppression of steady-state response to a harmonic excitation, a proportional and derivative feedback control is equivalent to a time-delayed control. The study of the stability issue focuses on a conflicting goal of achieving the marginal stability of the time-delayed vibration absorber and the stabili...
