This work focused on the study of efficient solutions for the improvement of the mechanical behavior and movement capability of industrial devices with mobile parts subjected to three-point bending load. To achieve the aim of developing efficient engineering solutions, several stages were followed. A sensitivity analysis was done to one of the beams in order to determine the influence of each variable in the mass and in the displacement’s parameter space. It has been shown that parameterizing the ANSYS input file is effective for finding out how sensitive is the system to the design variables studied. The results of the sensitivity analysis may be used in the future to choose the variable weights that will be used in optimization techniques and processes.
