Authors of this article note that one of the widely used in practice methods of strength calculation of structures is the finite element method (FEM). FEM is a procedure of approximate solution of differential equations. It was originally designed for solving problems related to the calculation of strength of structures, that is, to calculate forces, stresses and strains in solids.

The authors of this article note that the fast pace and modern construction make qualitatively new demands on building materials and structures. While great attention is paid to the production of glued wooden structures. Such designs on a number of technical and economic indicators are superior to metal and concrete have low component weight, relatively high strength and stiffness with sufficient reliability and durability. At the same time, negative characteristics of the wood (the dependence of the properties from its structure, defects, need for and considerable expense of quality timber, excessive massiveness of the cross-sections, creep under sustained loading, etc.) restrict the scope and impair the indicators of glued wooden structures. One of the ways to address these shortcomings and increase techno-economic efficiency – reinforcement of sections of glued wooden structures and elements of steel or fiberglass reinforcement. This can significantly reduce the consumption of wood, reduce Assembly mass, to improve the quality and reliability of wooden structures, working mainly in bending and compression with bending.

This article focuses on the technical means used by the customs authorities when they control oversize cargoes. Customs inspection efficiency improvement as one of the main forms of customs control during the implementation of sampling is possible by the use of technical means of customs control.

This article describes the ways to improve the automated system of technological preparation of manufacturing. The method for optimizing the planning of technological equipment based on the use of artificial neural networks was developed for the automated system of technological preparation of manufacturing.

The criterion of movement stability for executive or working body in non-contact linear drive is proposed for the first time. The criterion is determined by power method for the case of small-scale transverse oscillations of working body near the equilibrium position caused by external perturbations. Its validity is verified by a series of computations with parameters variation of mathematical model.
