Mechanism validation after stress concentration analysis mathematical calculated with safety factor requirements using dedicated software with friction factor mate

Abstract

It is feasible to use Computer Aided Design (CAD) and Finite Element Analysis (FEA) numerical simulation to validate the mathematical results obtained. Testing mechanisms in real world situations, prior to manufacturing, results in optimal designs and more reliable products. Simulation software tools evaluate the behavior of a system, improve the quality of data interpretation, and even increase product innovation. The present work shows the calculation of a simple mechanical system in two dimensions, involving the mechanical properties of the materials used, obtaining the maximum allowable load due to a required safety factor. The behavior of a mechanical element while in a stress concentration is shown along with the results obtained mathematically and with the dedicated software. Once the validity of the theoretical behavior (simulation) is known, the original design will be submitted showing the assembly with non-coincident meshing, the results obtained by the friction factor, the ISO clipping showing the volumes involved in a real situation, and the acquirement of the safety factor. The designer is shown a reliable method for decision making in the development of new equipment, modifications or even changes in the geometries and materials involved.
