Relevant for the JET-X Mission a post-processor of the Finite Element Code SAPV has been developed for the numerical assessment of the behavior of Mirror Module submitted to random vibration. Standard deviation and mean extreme values depending on the duration of time-excitation and on damping factor have been assessed for the most significant components of displacement and stress. The standard deviation values have been computed by combining by the square root of the sum of the square (SRSS) rule the results obtained exciting the system along three normal directions. This is consistent with the assumption that the three components of excitation are uncorrelated. We report in this paper the theoretical background and the most significant results.
