Nowadays the analysis of the Eigen frequencies of vibration has become one aspect to be considered in various industries. The study of the dynamic response, frequency of vibration and damping Eigen modes of complex structures depending on the loading conditions, it is difficult to solve using only numerical or analytical tools. This work presents software developed, MT Tremula, based in the LabVIEW, to obtain the natural frequencies for any mechanical system. In order to validate the developed Software a clamped-free beam was analyzed. The results experimentally obtained were compared with the numerical ones achieved using the ADINA finite element program.
