Applications And Research Of Composite In Plate-Cone Reticulated Shell

Plate-cone reticulated shell is a new type of space structures of half continuity and half lattice, it is a type of double-layer reticulated shell in which Ventral members is replaced by cone element. Researches for Plate-cone reticulated shell in our country and overseas is not very sufficient, the research focuses on discussion of structure forms and introduction of engineer practice. Composite material is a relatively promisng material, and the paper will firstly carry out the deep study on the applications in Plate-cone reticulated shell.In the forming technology of Plate-cone reticulated shell, this paper compiles procedure in Frotran language in order to create Pre-processing Program for Plate-cone reticulated shell, it can create each finite element model for force analysis only need to input a few geometric parameters, it can economize the Pre-processing work greatly for modeling, so that it can carry through analysis and design further for Plate-cone reticulated shell.This article carries on the static calculation, stability ansylsis and local buckling analysis in Composite Plate-cone reticulated shell using large finite element analysis software ANSYS, and summarizes the mechanical behavior of Composite Plate-cone reticulated shell to determine the main control factors. Then the main control factors of Composite Plate-cone reticulated shell are analyzed by the the point of view of different influence factors in the paper, especially by the lay up design of Laminated Composite Plates, to Summary the cprresponding structural design principles; And the paper carries on the reasonable design to Composite Plate-cone reticulated shell and Laminated Composite Plates using the structural design principles and the methods from related chapters , which fully dispalys the advantages that structure design and material design are at the same time; Finally,comparing with other materials Plate-cone Reticulated Shell, Plate-cone reticulated shell is more advantageous which prove the unique superiority in the mechanical behavior.
