The high frequency response of a beam carrying a rigid body at its middle under a point random force has been studied. Theoretical investigation has been carried out for both the spatial averaged response of the beam and the local response of the rigid body. The approximate expressions have been derived by studying the asymptotic behavior of the result of classical modal analysis. It is shown that the effect of the rigid body on the spatial averaged response of the beam is negligible and that the dependence on frequencies of the rigid body response is different from that of the beam spatial averaged response.
