In this paper, a method to accurately estimate the CG grms from the acceleration power spectral densities with an appropriate sigma value to estimate peak CG accelerations is discussed. The differences between structural engineers and/or test conductors within the space industry exist on how the data obtained from flight hardware random vibration tests are used to estimate QSLs. A commonly used approach is to consider the rms acceleration Center of Gravity (CG) responses of test articles undergoing random vibration tests. This requirement is verified either by test or analysis with engineers using different approaches to meet this requirement. Center of Gravity Quasi-Static Load Estimate Using Random Vibration Responses The quasi-static load (QSL) is often levied on flight hardware structural designers as a requirement.
