Abstract

Abstract

Random-turbulence excitation research of steam-generator inlet tubes simulated sector model under different pitch velocities has been done by using equivalent power spectral density（EPSD） method given by Axisa and Taylor et al. Compared the measured EPSD to Taylor and Pettigrew’s suggested guidelines, a peak of EPSD at f_R≈1 has been observed, which was closed to the guideline boundary. According to test results, the guidelines were been modified and new guidelines were been obtained which were more closed to actual vibration of tubes.
