Abstract

Aircraft structure using the flexible structure as their main part of the body. The body must be safe to maintain their stiffness and increase the safety. This is very important because aircraft deal with human life. The study of experimental modal analysis is to get the modal parameter like frequency, damping and mode shape. The modal parameter will be analyzed to know the dynamic characteristic of structure. It very significant to know the dynamic characteristics of the structure because dynamic loads acting on an aircraft during flight will be encourages the onset of the structural damage such as fatigue crack. This structural damage is often the major cause of failure in aircraft system. This paper will discuss about the experimental modal analysis on flexible rectangular plate structure using forced vibration method. The forced vibration will apply at a flexible plate using the impact hammer. Then the data obtain will be compared with the finite element model that have be done by other researcher
