ON AERO-HYDRO-DYNAMICAL SURFACES GIVEN BY ALGEBRAIC PLANE CURVES
Krivoshapko S.N.
Abstract
Aero-hydro-dynamical surfaces are the surfaces of floating bodies made by the nature itself or by the men. They are given by their main cross sections lying in the coordinate planes. The lines' forms and their parameters are chosen due to conditions of the future surfaces. Equations of some algebraic aero-hydro-dynamical surfaces of the third order and more are presented

OPTIMIZATION OF BUILDING STRUCTURES ON THE BASIS OF GENETIC ALGORITHM
Lesovic R.V., Klyuyev S.V., Klyuyev А.V.
Abstract
The technique of optimal design of bearing structures on the basis of genetic algorithm has been suggested. A design of steel frame with varying 9 parameters using the method of finite elements is considered as an example. The best variant corresponding to the volume minimum of the frame material is revealed.

CALCULATION OF PROBABILITY OF STRUCTURE DESTRUCTION BY MEANS OF THE SOFTWARE (PN-1.1) AND COMPARISON WITH Rzhanitsyn'S methodology
Kuz'michevskiy А.Y., Getman A.F.
Abstract
The method of the resource estimation of equipment and pipelines of nuclear power plants in probability aspect is described. The method is development of the classical approach of A. Rzhanitsyn to definition of probability of destruction of a design at static loadings. The method allows to consider quality of designs, the equipments and pipelines by criterion of their faultiness, including after carrying out of non-destroying test and repair of the revealed defects. Based on the method developed by one of modules of the computer complex is based on the Maple 12 to carry out the calculation of the probability of destruction, leaks and defects in equipment and pipelines of nuclear power plant, optimization of non-destructive testing and maintenance during operation. There are examples of resource assessment and the probability of destruction of nuclear power plant equipment.

KOMP'YuTERNOE TESTIROVANIE V PREPODAVANII MEKhANIKI
Gritsenko D.V., Kopnov V.A.
Abstract
This article addresses the main directions of the computerization process of the mechanical disciplines teaching in technical educational institutions. It gives a detailed overview of the computer monitoring of students' knowledge. To conduct such testing the authors present the programs named 'Test' and 'Training' which perform both educational and monitoring functions. There is a wide range of methods in which the programs may be applied. These methods have been evaluated during educational process and proved to have certain effectiveness.

DAMAGE DIAGNOSIS OF A HINGE SUPPORT BEAM
Ilgamov M.A., Khakimov A.G.
Abstract
The incision is a model for beam damage, specifically, for an open cross crack. It is shown that one can draw a conclusion about the presence of damage flaws judging by the first natural frequency of beam flexural vibrations. The incision coordinate, its depth and length are defined by three natural frequencies of beam flexural vibrations.

THE DYNAMIC OF ELASTIC-ACOUSTIC SYSTEMS
Shlychkov S.V.
Abstract
In the work, the dynamic properties of shell and its filling acoustic medium as the connected elastic-acoustic system are investigated. Computation model is elaborated on the base of the finite element method. The oscillation spectrum of partial and connected of systems is determined and compared in the range to 50 Hz. It is established that only region of the lowest frequencies of the behavior of the connected system is similar to partial.
