Abstract

Sound and vibration damping is the key aspect in the most of the structures. The viscoelasticity property can be used to reduce vibrations. Many polymers are used as a viscoelastic damper in Constrained layer damping(CLD) and Free layer damping. Sorbothane is basically, visco-elastic in the form of polymer. Visco-elastic property is related to the material exhibits properties of both liquids (viscous) and solids (elastic). The polymer Sorbothane is a thermoset by nature, polyether-based, polyurethane material. Sorbothane have shock absorption capacity and good memory, vibration damping characteristics and vibration isolation. In addition to this, Sorbothan polymer is a excellent acoustic damper and absorber. Damping loss factor is calculated for different Patches on cantilever beam with modal analysis on NI LabView and ANSYS.
