In this paper, a modal analysis is performed using The Finite Element Method (FEM) to a railroad tank car used to transport fuels and chemical products. Many of these substances are dangerous, so it is essential ensure the structural integrity of the units. The first 12 natural frequencies with their respective vibration modes of the structure were obtained. These results are used to determine safe conditions at different excitation frequencies and to avoid resonance problems during operation.
