Abstract
Quantitative values of structural damping factors for ground launched aerospace vehicles are seldom precisely determinable. This paper presents measured data from
a large vibration test program and shows correlation of these data with the amplitude of motion. Experimental structural damping factor values and amplitude of
vibratory motion from a vibration test are combined to show the amplitude dependency of structural damping factors. The experimental data show good correlation
of structural mode damping factor with the amplitude of vibratory motion. The data were obtained from flight control frequency response testing of shuttle orbiter
and ascent vehicles and structural mode damping factors obtained from Ground Vibration Tests, MSFC, Huntsville, Alabama, June 1978 through February 1979.
