摘要：
During the development of a new aircraft, the Ground Vibration Test (GVT) is an essential test and this work presents the results of the modal analysis performed in a small and flexible structure simulating an aircraft. The objective was identified, compare and explore different methods - Experimental Modal Analysis and Operational Modal Analysis- in order to obtain the modal parameters of the structure. The reliability of an experimental and operational analysis was verified by modal assurance criterion calculations between the experimental data and validated by comparison and correlation with a finite element model.
