Diseño y construcción de una máquina de ensayos sometidos a fatiga por flexión rotativa con capacidad de 294 N·m.

Abstract

The current technological project focuses on the construction of a machine designed to subject ductile materials such as steel and aluminum to rotary bending fatigue, following the ASTM 466-15 standard as an initial reference. This device will employ a mechanical system with an electric motor and transmission. The project development is based on thorough research, alternative comparison, and detailed design of key components such as the flexible coupling known as a cardan joint, responsible for transferring torque from the transmission to the shaft, along with comprehensive cost analysis. Each component was carefully selected through a rigorous process that included both static and dynamic calculations, considering key factors like durability, strength, safety margins, and operating conditions. The final machine design was brought to life using advanced software tools, with SolidWorks playing a key role in the structural analysis of the base. The device is expected to perform fatigue tests with a high level of reliability, ensuring accurate and dependable results.
