With this method, frequency domain peaks from different times become part of a composite PSD. During testing, then, this 1 second peak is considered to occur across the duration of the event. lake nebagamon wisconsin dnr

"WebbRandom vibration. Eq. (2.29) is not mathematically valid in the case of non-uniform flow because the power spectral density (PSD) of the excitation force, S F (ω)(=2G(ω)) depends on the axial location along the tube.To avoid this problem, the following two approximate methods are applied: 1. The frequency composition of the excitation force is considered … " - Random vibration testing instar engineering
