The Value of Limited Random Vibration Flight Data 640341

When sensitive parts of a spacecraft experience random excitation, it would be advantageous to determine a causal relationship between the source of excitation and the response. Power spectral density and cross spectral, density are factors in determining this relationship, if the response can be written in terms of the excitation. This paper derives expressions for these density functions in vector modal terms as an attempt to obtain physical interpretation of the random behavior.
Experimental verification may be achieved by combining wind-tunnel tests with full scale flight data.
