Training technique for topological structures designing based on a variable density body models

The article describes the training principles for topological structures designing. The ontology of subject area "The structural load-carrying layout designing" is given. The training technique of automated designing structural layouts using deformed solid body model with variable density is proposed. The educational process is based on creative pedagogy methods and is carried out in the environment of an educational and scientific virtual enterprise. The classification of training assignments for structural layouts designing is presented. Assignments are characterized by a multiplicity of engineering solutions and uncertainty in decision-making by rational structural layout. An example of a training assignment with the spatial design area, showing the aircraft fuselage structural layout designing in cutout region, based on deformed solid body model with variable density is given. The problems of assessment of training results the topological structural designing are considered. The results of the pedagogical experiment, demonstrating efficiency of the proposed training technique, are presented.
