Exploring Oberst Beam Standard Method for viscoelastic materials to increase test confidence and applicability / Lucas Ramos Carvalho, Eduardo Moraes Coraça
Damping treatments can be employed to mitigate vibration levels of structures near a specific resonance frequency. In the automotive area, constrained-layer dampers are the most employed, consisting on a viscoelastic layer bonded to a metallic-restrictor layer and to the structure itself subsequently. The damper's frequency performance is strongly dependent upon the temperature of operation, which means that there is a need to characterize this relation in order to choose the best damping material, thus optimizing the application
