Optimal Desing of Composite Box-Type Structures

The present paper considers the optimization methods of box-type thin-wall structures both in terms materials and calculation methods. These are widely used transport, construction other areas. example such bodies buses, trolleybuses, trams, camper vans, train carriages, emergency vehicles, mobile workshops, accommodation facilities others. At first global later local for preset exposure by system analysis, mathematical modelling IT-technologies were performed. Determination target function criteria, limitations is shown during optimization. Development a composite structure project was suggested including geometric simulation, selection material components whin-wall elements composition. For purpose comparison application nature biological organism combination panel separation principal organ systems providing its vital activity: locomotive, circulatory, inspiratory etc., described. It that similarly to an vehicle (non-uniform system) can provide general strength rigidity structural elements. When composing element, each variant considered as module with physical mechanical characteristics. Methods be applied nonuniform analysis formulae determine given flexural plate shell “equivalent” uniform described further. An optimal design shown. conclusion regard proposed method made means approach.
