For this study, A vibration attenuation of the vibration absorber that is attached to the flight structures was carried out. Flight structures are stabilized to allow for operations in various operating environments; however, as the size and weight of the flight structures are reduced, to meet the requisite performance, the operating-environment-induced vibrations lead to a degraded operating performance; therefore, the reduction of these vibrations should lead to an increased operating performance. The vibration absorber includes a compliant energy-storage device, such as a spring, and is mass secured to the energy-storage device. In this study, the research to prepare the anti-vibration design of the flight structures was accomplished, and the vibration of the flight structures was analyzed using the finite element analysis; accordingly, a vibration experiment for the verification of the result of the finite element analysis was also conducted. Further, the design guidelines of a tuned mass damper were obtained.
