| Abstract: | This paper investigtes the dynamic properties of linearly viscoelastic materials with the system identification method and presents the experimental result for two classes of viscoelastic materials.The testing device and the micro-computer aided measuring system are illustrated. The theoretical analysis and experimental results show that this method is very efficient to measure the dynamic properties of viscoelastic materials with large damping. |
