This article presents the frequency and damping characteristics of sandwich conical shell structures with electro-rheological fluid (ER) core. The dynamic characteristics of conical shell for different core to facing thickness ratio (tc/tf), length to mean radius (L/R) ratio and effect of cone angle on frequency and damping for different boundary conditions are carried out. The variation of damping characteristics of electro-rheological fluid core with electric voltage is also investigated. © Springer Science + Business Media B.V. 2008.

Free Vibration Analysis Of Truncated Sandwich Conical Shells With Constrained Electro-Rheological Fluid Damping

Springer Proceedings in Physics

The finite element code is developed based on the displacement field proposed by Wilkins et al. to find out the natural frequencies and loss factors of fluid filled cylindrical shells with a constrained viscoelastic layer in between two facings made of composite material. The fluid effect on the natural frequencies and loss factors are taken care of by the added mass of the fluid on the structure. Effects of the fluid height, ratio of core to facing thickness and facing fibre orientation on the natural frequencies and loss factors of cylindrical shells are presented.
