Caracterización de resistencia de las cuchillas centrales para molinos azucareros. // Resistance characterization of sugar mills central knives.
Abstract
El presente trabajo trata acerca de un análisis tensional y deformacional de la cuchilla central del primer molino del
Complejo Agroindustrial (CAI) “Venezuela”, con el objetivo de crear bases para una futura optimización del diseño y
encontrar el material idóneo que responda a las exigencias de fabricación y explotación de dicha pieza, con el mínimo de
costos fabriles. Para tal fin se han empleado técnicas de avanzada para el análisis de las referidas piezas, a través de
métodos numéricos, empleando el Paquete de Programas “COSMOS”, el cual brinda la posibilidad de obtener resultados en
forma de tablas y gráficos, que ilustran visualmente las zonas más tensionadas de la pieza, facilitando su localización.
Asimismo, se utiliza un modelo que facilita la resolución del problema con el empleo de las correspondientes ecuaciones
matemáticas. Finamente, los autores ofrecen recomendaciones para un futuro estudio del desgaste y la optimización del
peso y del volumen de la pieza que fue sometida a la investigación.
Palabras claves: Cuchilla central, molinos azucareros, método de elementos finitos.

Abstract:
This paper deals with a tensional and deformational analysis of the first mill central knife in sugar mills. It has the objective
of creating the basis for future optimization of design and also finding the proper material, according to the manufacturing
and working demands with a minimum manufacture cost. This is accomplished by means of advanced techniques in order
to analyze such elements through numerical methods, these programs give possibility to obtain results in tables and charts,
which visualizes the tensile distribution in all regions and make easy to detect dangerous zones. A model that facilitates the
problem solution is also employed, with its corresponding mathematical equations. Finally, the authors make suggestions
for a future study of wear and for the weight and volume optimization of the investigated object.
Key words: Central knife, sugar mills, finite element method.
