Sede Bogotá., ) Pelayo Robelto, Daniel Alejandro; Melo Daza, Pedro Fernando; Rodríguez Barón, Iván FelipeWhen studying the analysis of aeronautical structures II, knowledge is developed regarding the behavior of internal forces, deformations and stresses acting on a structure, its theoretical and mathematical bases, computational aerodynamics; knowledge in which software development can be applied and executed, opening the perspective to possible solutions and breaking limitations when performing different analyses and tests in the field of engineering, and in aeroelasticity where inertial, static and aerodynamic forces are taken to the limit. The study of modal analysis proposes to determine the natural frequencies, for this numerical methods have been used since the 40s, which allow to show the parameters in a computational way, however, for their validation a study that supports said simulations is required. Now, it is necessary to identify the relationship between numerical and experimental methods. For the numerical methods, it is necessary to evaluate the natural frequencies of a plane in boundary conditions (embedded-free) implementing the Euler-Bernouli theory (beam theory). For this purpose, the Ansys Discovery software will be used. While for the experimental process, it is requested to design and build a physical model of a plane in order to perform the corresponding data acquisition with acceleration sensors, a signal amplifier, equipment and NATIONAL INSTRUMENTS LabVIEW software. The delivered data will be analyzed and compared.
