Advanced Gun System (AGS) Dynamic Characterization: Modal Test and Analysis, High-Frequency Analysis.

Abstract

Dynamic characterization tests were performed on the Advanced Gun System (AGS) vehicle. The tests were designed to provide modeling information for high-frequency shock prediction codes, as well as finite element codes. These data obtained were also used to validate the modeling codes. The vehicle was analyzed in a full-up condition with the turret attached. A model analysis was performed to a maximum frequency of 100 Hz. The high-frequency characterization was performed up to 10 kHz. Methodologies to extract damping estimate up to 10 kHz were developed and implemented. Damping estimates up to 10 kHz were extracted from the structural data obtained during this test.
