摘要：Aluminum alloy and Aluminum composite plates have wide range of application like in airplanes,transportation, and construction industries. It has advantages over other materials due to its mechanical properties. It islow on cost and having high strength to mass ratio. It is important to do vibrational analysis because it gives theinformation about dynamic characteristics like frequencies and mode shapes. The frequencies are important to study.The structures’ designers consider the resonant frequencies and modal shapes in designing structures. The structures aregenerally subjected to vibrations like in the form of external excitation. The modal analysis help to design the structureswhich resist the effect of vibrations.This study is conducted to get the dynamic characteristics like natural frequencies and modal shapes of aluminum 6061plate which is isotropic. The modal analysis is conducted by both simulation and experimental methods. Theexperiment is performed on aluminum plate with attached inner tire tube sheet covered one third, two third and fullycovered of the one side of the plate. These parameters are compared with the plane aluminum plate. Finally results arediscussed.
