Abstract： The dynamic responses of the foam metal aluminum alloy beam was studied by Timoshenko beam corrective theory. The vibration equation of it was established by Timoshenko beam corrective theory, the expression for natural frequency of it and the analytical solution for forced vibration of it under the action of harmonic load were obtained.The comparative analysis of the spherical foam aluminum alloy beam and another foam aluminum alloy beam was carried out by practical calculation,and it was summarized that the spherical foam metal aluminum alloy beam had the better dynamic performances than others.
