MODELLING OF A METAL RIBBED CYLINDRICAL PANEL
The results of research of a newly developed metal cylindrical panel in the course of its shaping, and procedure of verification of the computer model are presented in the paper. The computer model of the panel under consideration, developed through selection of the finite element as a result of reshaping designated to ensure the formation of a plastic hinge in the points of junction between the principal element (the plate) and the stripes, makes it possible to perform a sufficiently accurate analysis of experimental and theoretical data of structures of ribbed panels under consideration. Application of the finite elements method in the course of development of computer models for the purpose of research of the process of shaping of ribbed panels at each stage of pumping of compressed air into the panel, makes it possible to assess the alteration of the stress-strained state of the structure and to identify the parameters of the new cylindrical ribbed panel with a high degree of accuracy, including such parameters as the radius of curvature R, swell ratio kр, and compression ratio kс.
