Paper Abstract

This paper deals with the mechanical structural analysis of the complete assembly system of the optics foreseen for the Italian Satellite for X-ray Astronomy SAX. Possible damages to the grazing incidence optical surfaces could have been induced by the strong environment during launch so that HNDT was adopted to obtain reliable data about amplitude and shape of the vibrational modes at some of the more critical expected frequencies. Computer simulation was also carried-out by the finite elements approach showing quite good agreement both in resonance frequencies and modes shaping with holographic analysis so that it was possible to take into account the attenuation factor resulting from holographic measurements.
