Computer modeling for intelligent evaluation of dynamic interaction of solids

The paper considers the problem of integrating the computer modeling results with experimental results of dynamic interaction of solids using digital processing of optical and X-ray images for subsequent analysis in an information intelligent system. The novelty is in the method of assessing the differences between the results of field and computational experiments based on use the fuzzy logic and fuzzy sets, as well as the procedure of switching to an index scale when forming a general assessment of differences for a set of the corresponding image points. The authors propose a concept and a developed algorithm for the joint cluster analysis of the results of X-ray and optical studies and the results of modeling the dynamic interaction of bodies. A computer model of solids interaction makes it possible to study the features of complex physical processes that occur when a hypersonic particle hits a spacecraft element, to substantiate the composition and design of real spacecraft elements, and to predict its damage depending on the parameters of elements and anthropogenic particles within certain limits. The simulation results can become a base for forming a data bank that will expand the limited set of results of computational and experimental modeling and field experiments. In general, the computer simulation results make it possible to prepare scientifically based initial data and recommendations for developing a protection design and a protection control system for an advanced spacecraft.
