Abstract
El objetivo de esta investigación ha sido analizar la esclusa de émbolo buzo diseñada por Agustín de Betancourt y Molina en 1807. Para ello, se ha realizado un estudio de ingeniería asistida por ordenador, concretamente un análisis estático por elementos finitos basado en el modelo tridimensional obtenido con técnicas de diseño asistido por ordenador mediante el software paramétrico Autodesk Inventor Professional, a partir de la planimetría original del expediente. Los resultados muestran que la posición más desfavorable ocurre cuando el émbolo buzo está completamente levantado, sobrepasándose los límites de elasticidad de los materiales. Por tanto, la conclusión principal es que la esclusa está mal dimensionada, aunque esto se debe a que las láminas sólo tenían un valor funcional o descriptivo, no habiendo sido llevada nunca a la práctica dicha esclusa. Sin embargo, el ingeniero español diseña un novedoso sistema de equilibrio émbolo buzo-contrapeso.
Highlights
The works and academic activity of Agustín de Betancourt y Molina, a pre-eminent Spanish engineer of the 19th century, served in training many engineers in Europe and helped to modernize his times
His years of work in the Inspection of the Canal of Castile (2), and the Imperial Canal of Aragon (3) constituted early experience that he would complete with his studies at the School of Bridges and Roads of Paris and with his trips throughout Europe. This gave him a full perspective of the European situation in this respect. His project was a possible economic alternative to the canals that were being designed in that period and for which he needed a new type of lock of specific characteristics: the plunger lock
Betancourt designed the plunger lock, The starting material was only the information available in the webpage of the Proyecto Agustín de Betancourt de la Fundación Canaria Orotava de Historia de la Ciencia (11). This webpage shows information related to this record entitled Mémoire sur un nouveau système de navigation intérieure, dated August 1807, presented in the Science Academy of Paris and published in 1808
Summary
The works and academic activity of Agustín de Betancourt y Molina, a pre-eminent Spanish engineer of the 19th century, served in training many engineers in Europe and helped to modernize his times. The main document by Betancourt regarding canals is entitled “Mémoire sur un nouveau système de navigation intérieure” (Report on a new system of inland navigation) (1), its purpose being to change the transport system to canals throughout Europe His years of work in the Inspection of the Canal of Castile (2), and the Imperial Canal of Aragon (3) constituted early experience that he would complete with his studies at the School of Bridges and Roads of Paris and with his trips throughout Europe. This gave him a full perspective of the European situation in this respect. His project was a possible economic alternative to the canals that were being designed in that period and for which he needed a new type of lock of specific characteristics: the plunger lock
