Аннотация: Using idealized models of the magnetosheath and magnetospheric magnetic fields, plasma densities, and plasma flow, we test for the steady state viability of processes mediating the interaction between the solar wind and the magnetosphere of Saturn. The magnetopause is modeled as an asymmetric paraboloid with a standoff distance of approximate to 25R(S). We test where on the magnetopause surface largescale reconnection may be affected by either a shear flow or diamagnetic drift due to a pressure gradient across the magnetopause boundary. We also test for the onset of the KelvinHelmholtz instability. We find that, for the solar wind and magnetosphere states considered, reconnection is inhibited on the dawn flank due to the large shear flows in this region. Additionally, most of the dawn and dusk equatorial region of the magnetopause is KelvinHelmholtz unstable, due to the presence of the dense magnetospheric plasma sheet and weak magnetic fields on either side of the magnetopause. This study is a followup to a previously published study of the solar wind interaction with Jupiter's magnetosphere.

Аннотация: Based on the equations of the dynamics of piecewise-homogeneous elastic material, parallel computational algorithms are developed to simulate the process of stress and strain wave propagation in amedium consisting of alarge number of blocks interacting through compliant interlayers. Computations of waves caused by localized impulse perturbations show that such amedium can be considered as isotropic only in the case of sufficiently thin interlayers. In the case of relatively thick interlayers, the anisotropy effects are observed which consist in the appearance of elongated wave fronts along the coordinate directions and characteristic oscillations of velocities and stresses because of the rotational motion of blocks. For the description of waves in ablocky medium with thin interlayers, the equations of the isotropic Cosserat continuum are applicable. As the thickness of interlayers increases, the orthotropic Cosserat continuum theory which takes into account the symmetry of elastic properties relative to the coordinate planes can be applied. By comparing the elastic wave velocities in the framework of piecewise-homogeneous model and continuum model, a simple method is obtained to estimate the mechanical parameters of the orthotropic Cosserat continuum modeling ablocky medium. In two-dimensional formulation of the orthotropic model the computational algorithm and the program system are worked out for the analysis of propagation of elastic waves. The comparison showed good qualitative agreement between the results of computations of waves caused by localized impulses, in the framework of the model of ablocky medium with compliant interlayers and the model of orthotropic Cosserat continuum.

Аннотация: In the framework of mathematical model of a block medium with elastic blocks interacting through compliant viscoelastic interlayers and its approximation on the basis of equations of the Cosserat continuum, the problems of periodic perturbation of a layer and of a half-space under the action of distributed and localized surface loads are solved numerically. The simple formulas are suggested to determine the elasticity coefficients of the moment continuum by given characteristics of the materials of blocks and interlayers, which provide a good correspondence of the wave fields received by means of the exact and approximate models. Parallel computational algorithms, based on models of the inhomogeneous elasticity theory and the Cosserat elasticity theory, are applied to the analysis of propagation of elastic waves in geomaterials with layered and block microstructure. These algorithms are realized as parallel program systems for GPUs (using CUDA technology) and for multiprocessor computers of the cluster type (using MPI library). Monotone grid-characteristic schemes with a balanced number of time steps in elastic layers or blocks and in viscoelastic interlayers are used. By the analysis of numerical solutions it is shown that the multiblock medium has a resonant frequency of rotational motion of blocks, and this frequency does not depend on the size of a massif and on the boundary conditions at its surface.

Аннотация: Mathematical model for the description of deformation of a porous material with a random distribution of pores is constructed on the basis of generalized rheological method taking into account the different resistance of a material to tension and compression. Phenomenological parameters of the model are determined by means of the approximate computations for the problem of static loading of a cubic periodicity cell with spherical cavities. Within the framework of this theory the fields of displacements and stresses around expanding cavity of spherical shape in a homogenious space are constructed. It is shown that the porosity does not change at the stage of elastic deformation. When the pressure increases, a zone of plastic compaction is formed in the vicinity of a cavity, and in a part of this zone the collapse of pores takes place. Engineering formulas for calculation of critical pressures of the elastic limit state and the limit state of a medium with open pores, and also the formulas for determining the radiuses of interfaces of zones of plasticity and compaction are obtained. A complex of parallel programs for numerical analysis of the dynamic deformation of porous materials on multiprocessor computer systems is worked out. By means of this complex a series of computations for deformation of the protection elements, made of metal foams, under the action of localizedim pulsive loads was performed. The random nature of distribution of the pores size is taken into account with the help of computer modeling. Computations allow one to estimate plastic dissipative part of the energy of impact.

Аннотация: Рассмотрен метод системного моделирования бортовой аппаратуры командно-измерительной системы космического аппарата. Дано описание модели и эвристического метода направленного пошагового проектирования, в результате которого строится модель, имитирующая структуру, свойства и методы функционирования командно-измерительной системы. Описана программная реализация инструментальных средств, позволяющих выполнять построение модели: задавать конфигурацию, коммутационные соединения и логику информационного взаимодействия.

We address a method for modelling of onboard equipment for the command and the measuring system of the spacecraft. The result of the method is the information and graphical simulation model that represents the specified level of details for the configuration and functions of the on-board equipment. A heuristic approach is used to support the model construction that allows a sequence of model changes in order to simulate the required specifications and functions of the equipment. The model is designed to simulate the operation of a command-measuring system. The command-measuring system is designed for command-measuring control of onboard systems, transmission of telemetric information to Earth control complex, measurement of current navigation parameters of a spacecraft's orbit. We have formally described the model of a command-measuring system, and also designed the methods and instruments allowing to present its architecture and a configuration of connections. The model's function rules are explicitly set in the knowledge base of the product. The rules describe the logics for operation of the command-measuring system: transfer of command information to spacecraft's systems, acceptance and transmission of telemetric information, conditions of the onboard equipment control, choice of interfaces for the equipment. The research is carried out for creation of the “Program-mathematical model of the onboard equipment command and measurement system”. The program includes the tools for model building and simulation. During the simulation it renders the sequence of actions defined for a specific model configuration. The software includes advanced configuration features models, statistical modelling of storage, management simulations, and analyze the results of the model. These functions allow a user to enter a variety of heuristics to analyze design solutions. The program was put into trial operation in the JSC "Academician MF Reshetnev Information Satellite Systems".

Аннотация: Процесс совмещенного литья и прокатки-прессования (СЛИПП) целесообразно использовать для производства длинномерных деформированных полуфабрикатов из алюминия и его сплавов, из которых изготавливают электрические провода, заклепки, проволоку различного размера для выполнения сварочных работ в электротехнической и радиоэлектронной промышленности, а также в космическом машиностроении. Способ СЛИПП является перспективным направлением обработки металлов, позволяет существенно снизить трудо- и энергоемкость производства, однако его промышленное внедрение сдерживает в том числе и отсутствие алгоритмов автоматического управления. Особенно это важно для создающихся в настоящее время агрегатов СЛИПП, в состав которых входят различные узлы, обеспечивающие кристаллизацию и деформацию металла, его охлаждение, калибровку (при необходимости) и смотку готовых изделий в бухты. Автоматическое управление должно обеспечить заданный расход металла, одинаковый во всех узлах агрегата, заданные значения температуры металла на входе и выходе из деформирующего узла, согласовать скорость вращения приемного намоточного устройства с расходом металла. Для этого необходимо создать математическую модель, реализовать её программно и визуализировать. Проведена постановка задачи моделирования и представлена упрощенная математическая модель на основе обыкновенных дифференциальных уравнений для управления агрегатом совмещённого литья и прокатки-прессования для получения длинномерных изделий из алюминиевых сплавов. Математическая модель для управления агрегатом СЛИПП реализована в программных продуктах WinCC 7.0 и Step 7 с применением языков программирования FBD и SCL. Разработана мнемосхема процесса, с помощью тегов реализована её связь с моделью. Приведено описание структуры программы в ПО Step 7, представлен вариант расчёта стационарного режима работы установки на мнемосхеме.
The Combined Casting and Rolled-Pressing Process (CC&RP) is used for electrotechnical-purposed aluminum rod production, which serves as half-stuff for manufacturing of different-sized aluminum wire, rivets, electrical and welding wire for electrical and radioelectronic industries. Depending on its properties, aluminum rod is widely used in the various industries, including space engineering. CC&RP method is a promising way of metal treatment, which is not yet widely implemented due to insufficiency of the automation algorithms. Automated control should provide specified values of metal consumption, temperature at the rolling mill, temperature mode of pressing node, rod temperature at the matrix end, intake device rotational speed in respect to metal consumption. For this purpose, mathematical model development, as well as its programming realization and visualization are needed. This paper provides statement of modeling task and simplified mathematical model of CC&RP method using the machine for aluminum lengthy products manufacturing. For each node of the machine ODEs is considered, that describes changes of process variables depending of time or coordinates. Initial conditions for each node input are determined from technological constants or previous node outputs. Further, the CC&RP mathematical model is realized with WinCC 7.0 and Step 7 applications using FBD and SCL languages. The process mimic panel is developed and connected with the model. The description of the program structure in Step 7 and the version of machine stationary mode calculation are provided.

Аннотация: The parallel computational algorithm for analysis of the processes of elastic-plastic deformation of a porous medium under the action of external dynamic loads is developed. This algorithm is based on the mathematical model taking into account threshold nature of change in the strength of a material under the collapse of pores. The algorithm is implemented in Fortran by means of functions of the MPI library. The parallel program system has been tested on clusters in computations of the propagation of plane longitudinal shock waves of the compression and in computations of the expansion of a cylindrical cavity in an infinite porous medium. The comparison of numerical results and exact solutions has shown their good qualitative and quantitative correspondence. Using the obtained algorithm, the process of propagation of elastic-plastic waves of the compression in a homogenous porous medium, accompanied by the deformation of a skeleton and the collapse of pores, is analyzed.

Аннотация: Slow-rate development of mineral resources in Siberia is connected with remoteness of mineral fields and deficiency in hard-surface roads. The approval of the government transport system program in Siberia requires boosting road metal production and quarrying expansion. Mined-out voids of depleted quarries disturb lands and remain bare for a long time. The situation in the Krasnoyarsk Territory is of particular concern. It is urgently required to find planting methods for mined-out ballast quarries. The obstacle is the traditional geometry of mined-out open pits, with steep walls and vast bottom flooded with atmospheric precipitations. Ecological monitoring of mined-out surface mines in the Krasnoyarsk Territory and most effective vegetation of mined-out voids shows that, given the local climate (long cold winter and short hot summer), population of trees is higher on the southern and eastern pit walls, where moisture content is higher and trees are less dehumidified under the sun in simmer; of no less significance is flatness of slopes and weak inclination (3-5°) of roads towards pit walls, as well as presence of fertile soil layer in the walls. On special purpose plots of land 0.2 ha in area, trees have been counted per each element of a quarry, which makes the basis to develop recommendations on environmentally optimal shape of quarries: maximum area of the southern and eastern pitwalls to be slightly sloping (15-24°), minimum technologically reasoned area of bottom is shifted northwestward. The study is in accordance with the Fundamental Research Program of the National Academies of Sciences for 2013-2020 and the research plan of the Nauka Design and Engineering Center, ICT SB RAS for 2013-2017, under the project "Information Support Models and Technologies for Evaluation, Forecasting and Management of Regional Eco-Systems, Territorial Infrastructure and Natural and Industrial Safety".
