An Experimental Study on the Vibration Characteristics of Aluminum Honeycomb Core Sandwich Structure

초록

The vibration characteristics for aluminum honeycomb core sandwich(AHCS) structure are investigate. This structure has the merit of aluminum alloy and sandwich structure. First part of this paper is an experiment for aluminum honeycomb core sandwich plates which have different face thickness and cell sizes. The experimental data are compared with analytical solution and the simulation data obtainde from NISA(Numerical Integration Elements for System Analysis, Finite Element Method Package Program)Second part is an experiment for idealized mid ship section of high-speed vessel which is composed of aluminum honeycomb core sandwich plate, and then compare experimental data with the NISA simulation data.
