ANALYSIS OF DAMPING COEFFICIENT FOR VISCOUS DAMPER

Project aim is contribute in torsional vibration theory and their practical experiences used in dampers which are widely used in automobile application & civil applications. Project is sponsored by “Hodek vibration Technologies pvt ltd”, pune. This is largest dampers manufacturer of torsional vibration dampers for diesel engines. 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
