Finite element analysis of a jib crane jib with different types of steels

Introduction: cranes are equipment used in industry, construction, manufacturing and maintenance, currently they are in high demand by the industry, because they allow lifting and moving loads within their range, Objective: Determine the relationship between the type of steel used in the manufacture of jib crane jibs and the natural frequencies of vibration. Methodology: A quantitative investigation was carried out, it had a pre-experimental design, 7 qualities of carbon steels with different mechanical properties were used, through modal analysis with the ANSYS software their dynamic responses were found. Results: It was found that the most important vibration mode is number 2, the natural frequency is 19,63 Hz; comparing the other values of the different materials vary by approximately 1 %. Conclusions: The purpose of this investigation was to evaluate the types of static and dynamic behavior of a crane of seven different qualities of steel, the mechanical properties such as yield stress, tensile stress, do not influence the natural frequencies of the structure, it is in other words, it only influences if the mass (density of the material) and/or the geometry is varied.
