Abstract

This paper presents the vibration analyses of truss core panel. Truss core panel is newly devised lightweight core panel and has general versatility. The vibration analyses and excitation experiments to obtain the vibration characteristics such as natural frequency and natural mode are conducted. As a result, comparing with the flat panel which weight is equal to the truss core panel, it is proved that truss core panel has tremendously high natural frequency compared with that of the flat panel. It is expected on the process of generalization bending rigidity of truss core panels can be underestimate because the stiffness of the truss core panel at the edge parts is less than that of core parts of the panel. Therefore in order to consider the effects of edge parts, bending rigidity of six different size panels with same wide edge are analyzed and proved that by enlarging panel size, the proportion of edge parts become relatively less and the bending rigidity per ideal sandwich panel close in to constant number, over 42%. On the other words bending rigidity of the truss core panels, which edge parts are not nominal, can be underestimate.
