Paper Abstract

Dynamic characteristics of composite laminates and composite isolators are studied in detail, and an optimum isolator for a 500Kg satellite is designed. Simulations are performed in order to determine the optimum geometry as well as dynamic characteristics of the isolator. It is found that increasing fiber angles of the ribs causes periodic sinusoidal change to the ratio and frequency. The first lateral frequency increases with thickness of skins, ribs and closure rings, but decreases with rib thickness. Thickness of closure rings produces little effect on the ratio. Based on these simulation results, isolator for satellite suppression is designed. The feasibility are verified by finite element analyses.
