  • About stochastic similarity functioning of systems "means- equipment-technology-production" (METP) at the intensified hydrothermal treatment of leather shoe materials

    It is presented in article that the technique of determination of stochastic similarity of functioning of one of subsystems of the intensified hydrothermal treatment - moistening of details of top of footwear. According to the offered technique there were received to be expressions for determination of output parameter of process "moistening" - the module of elasticity of skin and relative deviations of characteristics the subsystems proving similarity functioning of considered subsystems in stochastic sense. According to the offered technique expressions for determination of output parameter of a subsystem of "moistening" - the module of elasticity of skin and relative deviations of independent parameters of process of the vacuum and sorption moistening, providing with the possibility of forecasting of the minimum duration of processing were received.

    Keywords: stochastic similarity, means-equipment-technology-production system, the processing intensified hydrothermal treatment, the vacuum and sorption moistening, the determined similarity, tanning and shoe materials

      Methods of mathematical (geometric) modelingare often used in the current research of multivariate processes and their optimization tasks combined with traditional mathematical methods of experiment planning. This simulation is carried out by methods of descriptive geometry, its practical valueis a graphical representation of the functional relationships of the quality from factors and parameters that defines a process with number of variables more than three. Definition’salgorithmsof the optimization based on the Radishchev drawingin the article are given to ensure the visibility of images and solve certain technical problems.The graphical model of the process optimization of joining parts of garments was constructed.

    Keywords: Technological process, Optimization, Modeling, Descriptive geometry, Multidimensional space, Radischev drawing, Hyperplane, Hypersurface, Algorithm, Factors, Parameters.

  • System synthesis in real time of intellectual and adaptive management mekhatronnym object changeable structure

    In article for stability conditions in "small" the synthesis algorithm in real time of optimum discrete anticipatory control is received by mekhatronny object which together with algorithm of an assessment of a condition of the discrete filter of Kalman realize an electronic adaptive control system. In "big" it is offered to apply management of mekhatronny object to the maximum speed with neyrose-tevy realization and intellectual realization on "golden rule" of the person, making the decision. System synthesis of offered algorithms in real time realizes intellectual and adaptive system of anticipatory management of mekhatronny object of changeable structure.

    Keywords: mekhatronny object of changeable structure, criterion of the generalized work, an assessment of signals of the management, predicting model, criterion of a maximum of speed, neuronetwork realization to the maximum speed; realization on "golden rule".

  • Assessment of criterion of the generalized work at management optimization mekhatronnym object changeable structure

    The mathematical model of functioning of mekhatronny object of the changeable structure is given in article, described predicate and differential and predicate raznostny by the equations. Expression for an assessment or a changeable part of discrete analog of criterion of the generalized work is deduced by optimization of management by mekhatron-ny object of changeable structure.

    Keywords: mekhatronny object of changeable structure, an assessment of criterion of the generalized work, predicting model, optimum algorithm of management with predicting model, the predicate and differential equations, predicate raznostny the equations.

      The current work considers the problem of arrangement optimization of non-convex polyhedrons into a minimal height parallelepiped container. The no-fit polyhedron based algorithm is proposed to solve described task. The no-fit polyhedrons are used not only for providing conditions of the polyhedrons mutual non-intersection but also for finding the placement points. The current paper provides the block diagrams and the pseudo code of the algorithm. Some examples and computational results are also given for public input data. 

    Keywords: packing, no-fit polyhedron, non-intersection, optimization, arrangement

  • On the question of using materials of construction in road-transport system

    Listed analysis of the argil lo-gypsum (gaja) land deposit in the Rostov region with the intention of developing gypsum binding materials that used in the capacity of materials of construction in the highway engineering

    Keywords: materials of constructions, gypsum binding materials, land deposit, road-transport system

  • Calculation of elastic-plastic torsion absorber

    Currently most used energy absorbers can be represented classic spring-damper scheme in which the binding is the presence of the elastic work item and damper. Applied to seysmoudarnomu works best security systems installations are systems that do not have elastic elements. For hard metals, which are material for the work items absorber characterized by the appearance of a tooth during the deformation strength. For the calculation of the power characteristics of the work item should be modeled phenomenon associated with the formation of the yield drop. Modeling of the phenomenon of this article.

    Keywords: Dynamic loading, uprugoplastichesky deformation, deformation chart, power absorption, tooth strength

  • Rationale for the design features energopoglotiteley seismic structures

    Currently actively promote seismic associated with the use of special devices, so-called energopoglotiteley. This paper shows that the design energopoglotiteley advisable to make so that the work item had torsional strain. These EPA bdut have maximum energy absorption with minimal weight. Designs of EPA.
