An efficient method for constructing an approximate analytical solution to the contact problem of the penetration of a spherical indenter into the soft elastic layer lying on a rigid elastic foundation is proposed. The method permits to obtain the problem solution effective for the full range of the problem characteristic geometrical and physical parameter values. Some cases when Young’s moduli of the layer and the substrate differ more than a hundredfold are analyzed. The obtained contact stresses for different values of the foundation stiffness are compared with the formerly known results for the nondeformable foundation case. It is shown that when the elastic properties of the layer and the substrate differ a hundredfold, maximum difference between these results is less than 3%. The relationship between the pressing force and the radius of the sphere is determined. The question is put owing to the control problem of the thin coatings elastic properties.

The inverse coefficient problem for the second-order operator in the simply connected domain with the piecewise-smooth boundary arising in the theory of the deformable system vibrations is investigated. The solution method for the inverse coefficient problem based on studying Cauchy problem for the first-order differential equation with variable coefficients is offered. Both direct and inverse problems are solved on the ground of the difference approximations method. The reconstruction of the variable shear modulus of various types, obtained at both accurate and noisy input data, is resulted.

The spatial contact problem for the flexible wedge is investigated in the quasi-static formulation when two identical elliptic rigid punches are symmetrically impressed into one face of the wedge under friction. The other wedge face is stress-free. The contact domain is accepted unknown. The motion of the punches perpendicular to the edge of the wedge is considered. In this case the punches can move either towards the edge or from the edge. Using the known Green function for the three-dimensional wedge, the contact problem is reduced to the integral equation with respect to the contact pressure. Galanov’s method is used for solving the integral equation which permits to determine the contact domain and the contact pressure simultaneously. The numerical analysis is made for different values of the friction coefficient, wedge angle, and the distance between the punches.

The research results of the adhesive properties of ultrathin carbon films on sapphire by the sclerometry technique are presented. Both scratch testing parameters and adhesion strength of bond between the amorphous carbon film and sapphire are determined. Adhesion forces have amounted to the value of F₂ = 1.58 mN by the carbon film thickness of h ? 217 nm. The adhesion bond strength of a-C/sapphire couple has amounted to the value of Н₁₂ = 9,48 · 10^−20 J. Thus, the adhesion strength value of carbon film/sapphire has turned out 1.8 times less than, for example, of Au/SiO₂ couple. Scleroscopic tests for the a-C amorphous carbon film on sapphire are performed. Hardness value has amounted to H_SCR = 0.016 hPa which appears far less than hardness of the carbon films obtained by the magnetron sputtering in vacuum. The surface morphology of carbon film scans is investigated by the atomic force microscopy. The carbon film scan roughness is estimated, it amounts to 60 nm.

An innovative approach to the intelligent electronic interactive documentation of the mechatronic production facilities — the creation of smart-passports is presented. The approach relevancy is dictated by the need for such facilities to have an organized document flow of the tooling data, information exchange of data containing in particular test results for the geometrical accuracy of the production facility and the product machining accuracy. Specific features of every production facility under the operation programming are usually left out.

The approach to the generation of the solution sequence technique in the knowledge system is recommended. The terminological nature specificity of the knowledge system building typical of such object domain of the mechatronic processing equipment as machine tools is emphasized.

The problem on the stationary tool trajectories instability relative to the workpiece taking into account the periodic parameter variation of the interacting subsystems and of the dynamic coupling formed under cutting is considered. Parameter changes are caused by cyclic variations of the workpiece stiffness in the direction normal to the rotative axis, as well as variations of the allowance for machining periodic with the period of its rotation. It is shown that the periodic parameter changes induce the instability mechanisms not analyzed before. Moreover, in this case the loss of stability is basically dependent on the spindle speed. In addition, the instability is also associated with the kinematic perturbations caused by the periodic component of the support longitudinal feed velocity. Some examples of instability depending on the mathematical model parameters of the cutting system are given.

The analysis of the “risk” concept as a sociocultural phenomenon is carried out. The sociocultural basis for risk as one of the human being’s characteristics in the world and an essential component of the human activity is defined. The basic strategies of the contemporary individual behavior are considered since the nature of risk itself and the attitude towards it in the society differ widely versus the society type. The concept of the “individual risky action” is revealed. The factors contributing to the uncertainty and risk are described. In the process of the risky activity, the individual comes up against the situation of voluntary or necessary risk whose resolution depends on his action or inaction. In this respect, the assessment system of the risk acceptability and the adverse consequences connected with it in various scopes of activity are investigated. The specific nature of the individual risky action in the modern society is proved. Risk minimization methods versus the individual behavior strategy are analyzed.

The current status of the helicopter engineering in Russia is considered, the development prospects of the industry are evaluated. In the given period, the capital assets consolidation, and big business creation are being completed. Their manufacturing programs are aimed at the priority directions of the Russian aircraft industry. The significance of the chosen theme is caused by the role which the helicopter industry plays in forming scientific and economic potential of the country. At the present stage of the Russian economy development, problems on the organizational arrangement, divercification, entry into new markets become more urgent for helicopter equipment producers. In this regard, the focal points of the efficient manufacturing process control are considered by the example of the “Russian Helicopters” company. The following figures are analyzed: the Russian and world market shares of the “Russian Helicopters” company, operations efficiency improvement, development of new trends which will become additional sources of revenue.

The correlation issues of the state regulation organizational and institutional component of the foreign trade activity in Russia are considered. The factual data on the federal executive bodies operation during the period from 1992 to 2011 is gathered and analyzed. With consideration of these indices, the basic elements of the mechanism of forming path dependence in the foreign trade activity are selected. The key element of this mechanism is the cyclicality of the organizational and institutional development. In terms of the organizational component, the cycles under discussion are time ranges — from maximum to minimum amount of the performed organizational changes. In terms of the institutional component, these cycles are time spans when the priority of the certain trends of the state regulation and measures of state support for the foreign trade activity is observed. The perceived cyclicality is determined by the great accumulation of the factors of the organizational and institutional imbalances in the institutional system of the foreign trade activity. These imbalances are regarded as temporary discordance in the sphere of the legal support for education, abolition and functioning of the executive authorities responsible for the regulation and support for the foreign trade activity.
