Abstract
This paper presents experimental modal analyses performed on rectangular panels made from a HexWeb HIII aluminum honeycomb core and 2024 T3 aluminum face plates, which will used in the main structure of the Brazilian Geostationary Satellite This type of structure is commonly used in the aerospace industry because its low density and high mechanical strength. Tests were conducted using an impact hammer for exciting the structure and a Laser Vibrometer to measure the responses. Data acquisition was performed using the Labview / NI CompaqDAQ platform. Frequency Response Functions (FRFs) were generated and analyzed through routines elaborated in MATLAB software. Finite element models were also developed using the ANSYS APDL software. Based on the experimental data, numerical models were adjusted, improving the theoretical-experimental correlation.
