RESUMENSe desarrolló una simulación computacional mediante el método de elementos finitos del comportamiento mecánico del modelo de una broca de perforación tipo PDC en estado estacionario, tomando un instante de tiempo del movimiento rotacional. Con el propósito de simplificar el análisis y facilitar el cálcu-lo computacional de los estados de esfuerzo y deformación presentes tanto en el cuerpo como en los cortadores de la broca, se consideró solo las fuerzas mecánicas generadas por la interacción cortadorroca, descartando cargas térmicas, de vibración, y de impacto, así como el desgaste de los cortadores generado por la fricción. Con los resultados obtenidos mediante el software de elementos finitos se estableció la condición más crítica de operación de la broca bajo las condiciones y simplificaciones mencionadas.Palabras clave: Equilibrio estático, Broca PDC, modelo, Simulación computacional. ABSTRACTThere developed a computer simulation using the finite element method model of the mechanical behavior of a PDC drill bit steady state rate, taking a time instant of the rotational movement. In order to simplify and facilitate the analysis of computational stress and deformation states present in both the body and the drill cutters are considered only mechanical forces generated by the cutter-rock interaction, discarding thermal loads, vibration and impact, as well as wear of the friction generated by the cutters. With the results obtained by the finite element software is the most critical set of the bit operation under the conditions and simplifications mentioned.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
