On the Modeling of Isolation and Vibration Control Using Laminated Composite Materials

Abstract

This paper presents a comprehensive study of the influence of various composite structure characteristics, such as stacking sequences and fiber orientations, on the dynamic behavior of glass fiber reinforced composite (GFRC) plates for modeling isolation and vibration control levels. The dynamic behavior of GFRCs with fiber volume fraction of 0.6 and fiber orientations of 0°, ±35°, ±45°, and 90° was investigated numerically using Solid works software, then verified experimentally using B&K data acquisition analyzer. The numerical and experimental results were presented and analyzed to obtain the optimum configuration for controlling vibration nature using the Taguchi technique. The results show that the lamina orientation of 0° had the dominant effect on natural frequencies, while 90° lamina orientation is the foremost factor in damping behavior.
