Research object - the dynamic stress-strain state, thermal contact interaction and stability of thin-walled elements of constructions, manipulation systems, locomotion anthropomorphic type system, a complex dynamic system, parallel algorithms, quasisystolic structure. Purpose of work - the development of techniques and algorithms for calculation of composite thin-walled elements under the actions of complex loadings and the development of mechanical and mathematical models and methods of research concerning load-bearing ability, amplitude-frequency characteristics of thin-walled constructions, the development of models, methods and algorithms the optimization of structural parameters and regimes management manipulation systems, development of new methods and algorithms for complex evaluation of complex dynamic systems. Research methods - methods of continuum mechanics, direct methods of ordinary differential equations, analytical and numerical methods for solving the boundary value problems, experimental methods, methods of the optimal control theory, digital filtration theory and the parallel computing. A simplified version of refined theory of geometrically nonlinear deformation of thin transversally isotropic shells is proposed and substantiated. A mixed finite element scheme with respect to the calculation the composite layered shells is constructed and theoretically grounded. A mathematical model of free vibrations of laminated plates with consideration of discrete components is proposed. A new theoretical and experimental approach to determine the elastic properties of composite beams is proposed and implemented. The generalized two-parameter model for the investigation of contact interaction of solids through the thermoviscoelastic layer is constructed. The methods of the parametric optimization are developed and corresponding algorithms for solving of problems of combined optimization for structural parameters and control modes of closed manipulation and anthropomorphic locomotion systems. A mathematical model of human walking from the tibia-foot articulated orthesis is constructed. The technique of comprehensive evaluation of large real complex dynamical system with hierarchical-network structure is proposed. The schemes of specialized hardware to effective execution the highly-parallel algorithms for some variants of digital filtration are developed and investigated. The results are used to quantify the influence of the strength of bundles of structural elements such as multiply layered composite shells of revolution, Yuzhnoye State Design Office and during conducting research at the Lviv National Medical University named Danylo Galytsky and software engineering to evaluate and functioning of condition and quality for track and stations property Ukrzaliznytsia Product Description popup.authors Бутитер І.Б.
