Most important phases of development optimization of complex structure

Abstract

The paper is concerned with most important phases of formation and development optimization of complex structure. A formal approach to multidisciplinary optimization of complex devices is developed. The stages of optimization of complex devices: the choice of models of analysis, design variables, functional objectives and constraints. Optimization techniques are classified as direct; the first and second order; stochastic; linear and nonlinear programming. The applications of different types of Super Computer Simulation and Optimization Based Design / Engineering (multidimensional, structural, topological, parametric, multicriteria) are shown. On the basis of a mathematical model that takes into account the spatial and temporal fields of different nature (electrical, magnetic, elastic deformation, mechanical and thermal) with use of optimization genetic algorithms and the flexible polyhedron method, the complex structure is developed, which is characterized of reduced weight and size and high efficiency.
