The cylindrical curved structure has been employed in many engineering applications, like aircrafts, automobiles, ships, and other industrial machines. Since structures are usually vibrated with different level due to external regular or random loads, the failures in structure can initiate from the vibration by severe dynamic load and structural resonances. So the study of vibration and dynamic characteristics of cylindrical structure is an important work in engineering field.
This paper has applied the constrained viscoelastic layer damping treatments to a cylindrical aluminium shell. Experimental natural frequencies of cylindrical shell having viscoelastic core and aluminium face sheet skin and base are compared with those of the finite element method by using ANSYS software. The presented results show that the sandwiched viscoelastic damping layer can effectively suppress vibration of cylindrical aluminium structure.
