Torsional vibration in engine & use of viscous damper

vibration

Aim is takes part in torsional vibration theory and their practical experiences used in dampers which are widely used in automobile application & civil applications. This report paper highlights a number of important considerations for the torsional viscous damper system as well as design philosophies to assess and mitigate the risk of torsional failures. Damping properties are of significant importance in determining the dynamic response of structures, and accurate prediction of them at the design stage, especially in the case of light-weight, wind-sensitive buildings, is very desirable. Unfortunately, damping parameters cannot be deduced deterministically from other structural properties and recourse is generally made to data from experiments conducted on completed structures of similar characteristics. Such data is scarce but valuable, both for direct use in design and for furthering research into the phenomenon of damping. So use of damper is very much useful to reduce the torsional vibration. So viscous damper is mostly use for this purpose.
