| Abstract: | The work on vibration control of machines and structures incorporating viscoelastic
materials in suitable arrangements is highlighted for situations involving vibration excitations over a broad frequency range.The principle involved is that of vibratory energy dissipation due to damping as a result of deformation of viscoelastic materials. The characteristics of viscoelastic materials have to be suitably modelled in view of their
dependence on several factors like type of dynamic excitation temperature strain etc.The main objective of the paper is to review some of the salient work done at I.I.T Delhi relating to constrained layer damping for structures optimisation studies and support damping for rotor systems Some results which have either not been published or are not easily available are also included. Brief reference to related work carried out at other places is also made the list being by no means exhaustive due to space constraints efforts have been made to predict the future trends in theoretical and experimental work in the
analysis optimisation and use of viscoelastically damped structures |
