Abstract
La tracción animal como fuente energética tiene una amplia utilización en la agricultura de Oaxaca, México. Por tal razón se desarrolló un nuevo arado de tracción animal para realizar las distintas operaciones que se requieren durante la labranza. Con fines de la optimización se hizo necesario analizar la resistencia de los elementos estructurales de dicho arado mediante el método de elementos finitos. Como primer paso se desarrolló el modelo geométrico con la herramienta computacional Cosmos DesingStar 2008, y la definición de las propiedades mecánicas de los materiales empleados en la construcción del arado, así como la definición de las condiciones de borde y cargas. Los resultados mostraron que la estructura resiste las cargas aplicadas durante el trabajo con un coeficiente de seguridad de 2,46, la magnitud de las deformaciones resultantes se limitaron a 0,0005 m. Se evidencia que los materiales empleados en la construcción del arado garantizan la resistencia y rigidez requerida para el trabajo sin fallos de sus elementos y órganos de trabajo.
