Elasto-plastic model to determine the maximum force for shaft straightening process

This paper shows the development of a mathematical model based on elasto-plastic behavior of materials in order to determine the bending moment and the maximum straightening force required to repair a bent shaft. The importance of this work is because many machines use shafts to transmit power and movement, and these elements can suffer permanent deflections during operation cycles. An appropriate reparation process can increase the life of these elements significantly. Knowing the mechanics for a straightening process is essential for design, processes and maintenance engineers in charge of systems that use these elements (shafts)

La importancia de este trabajo radica en que muchas máquinas usan ejes para transmitir potencia y movimiento, y estos elementos pueden sufrir deflexiones permanentes durante sus ciclos de operación, de tal modo que un proceso adecuado de reparación puede incrementar la vida de estos elementos significativamente. Saber la mecánica del proceso de enderezamiento es esencial para los ingenieros de diseño, manufactura y mantenimiento a cargo de sistemas que usan este tipo de elementos (ejes)
