Resumen


Las mallas tensegríticas de doble capa (MTDC) son estructuras de Tensegridad que contiene dos mallas traccionadas paralelas, unidas por otra capa intermedia compuesta por elementos comprimidos y traccionados verticales y/o diagonales.
Este trabajo presenta inicialmente un breve repaso sobre las propuestas de MTDC que se han realizado hasta el momento, exponiendo luego una nueva metodología, eminentemente geométrica, para la generación de este tipo de estructuras tensegríticas.
Tras aplicar la propuesta de Otero para generar mallas de doble capa (MDC) convencionales, se procede a realizar Manipulaciones de Rot-Umbela en las capas inferior y/o superior para convertir dicha estructura en una MTDC. Las Manipulaciones de Rot-Umbela consisten en la apertura de cada vértice en un cierto polígono, al cual se le aplica una rotación o giro particular. Se consigue así un potente sistema para “tensegritizar” MDC convencionales y abrir una línea de investigación muy interesante en el campo de la Tensegridad.
