The project aims to develop a set of computational methods for mathematical modeling of the basic phenomena which limit the life of structural elements and control systems of spacecraft: long-term strength in the joint action of thermo and radiation fields, which can change cyclically over time, large deflection under unsteady loads and their effects on management system, shock from the impact of micrometeorites, sound management of energy consumption to support the functional ability of electromechanical (flywheel and gyrodines) spacecraft control systems and study of numerical solutions performed by established methods. Analytical methods of investigation are: the methods of optimal control, variational methods, asymptotic and numerical: simulation for solving optimization problems, problems of mathematical physics. Created new equation of state for creep and damage. Developed and investigated methods of refinement matrix mismatch between coordinate systems of astrosensors and AVS. Numerical and experimental investigation of shock deformation and fracture plates was done. The novelty of the work is to develop new methods for calculating long-term strength at high temperatures, which are periodically changed, impact the dynamics of rods systems for large deflections, methods of integration of the executive controls of the spacecraft. The results are of interest to specialists in the field of solid mechanics and control of moving objects. Product Description popup.authors Аврамов К.В. Асютін А.Д. Багмут І.О. Бреславський Д.В.
