Abstract

Background. Mechatronics products are widely used in many advanced technologies and systems of the modern economy – computers, instrumentation, mechanical engineering, aircraft and shipbuilding, medical equipment. The reliability of heterostructures that make up the fundamentals of mechatronics, used in extreme conditions both on land, under water, and in space, largely determines the operability of complex equipment. The subject of the article is connected with the synthesis of algorithms and the construction of models of nanodisruptions of heterostructures is relevant in the conditions of the fourth industrial revolution. The aim of the work is to increase the reliability of heterostructures based on its prediction based on the created mathematical models, which ensures the reliability and competitiveness of complex technical systems, including weapons and military equipment.
Materials and methods. Three main methods of analysis are used: generalization of information on failures, instrumental failure studies, mathematical modeling of processes leading to failures using deterministic models of mathematical physics. It is shown that 60 to 90 % of product failures are due to compounds of dissimilar materials, the main causes of which are failures of welded and soldered joints of multilayer structures and filled compounds of dissimilar materials: amorphous, crystalline, conductors, semiconductors and dielectrics, organic and inorganic, monolithic and porous. The model of heterogeneous structures is constructed on the system of Lame equations for displacements in polar coordinates in a matrix form representing a transcendental equation with respect to the eigenvalue of the equation sought by the Muller method.
Results and conclusions. As a generalized heterogeneous structure, the nanostructure of J.I. Alferov; A multiphase anisotropic structure is proposed from heterogeneous materials such as fractal bonded and free clusters. A new effect of local corrosion in hot urban water supply pipes is established under the action of vibroimpact loads of moving vehicles in conditions of intensive urban traffic. Algorithms for analyzing failures of heterostructures, analytical algorithms and models of generalized heterostructures, including electric power, are given. Finite-element models of stress fields for solving plane and spatial problems are described. The algorithms of failure dynamics of compounds of dissimilar materials are given.
