Large-scale work to create a Russian engineering analysis system involves the implementation of a considerable number of specialized tasks, each of which requires an individual approach and specific solutions. The calculation of pipeline systems that can most easily be performed in the version using rods is no exception. Such an approach is the most effective in terms of increasing the speed of calculations, increasing the dimension of the tasks performed, and most importantly, in simplifying the modeling procedure. In this paper, the authors consider the option of determining the stiffness matrices of a spatial element for modeling of pipes, which underlie the full engineering analysis of pipeline systems. Verification examples that confirm the reliability and correctness of the obtained solutions are presented.

With the rapid development of oilfield information construction, the requirements for the analysis of oil well production are also getting higher. The traditional method, which is by experience, cannot meet the demand of oilfield information construction for the analysis accuracy. Based on some common problems in the analysis of oil production, this paper designs and implements the oil well production engineering analysis system based on NET. The design of the system mainly includes two parts. One part is the calculation of temperature and pressure field of the wellbore and the other part is the drawing of system efficiency control chart. This system can provide the distribution results of temperature and pressure of the wellbore during the production process, and according to the system efficiency control chart, we can accurately determine the production situation of oil well. This system has the advantages of simple operation, accurate calculation, clear analytical results, and comprehensive analysis.

Abstract Research relevance is determined by the need of agricultural producers of Nizhny Novgorod Region to increase the profitability of sugar beet cultivation and to reduce seed losses at sowing. Another important factor is optimal energy efficiency of sowing machines, which can be achieved by reducing the draft force input required to operate the working parts. Leading approach to the research of this issue is to conduct a multifactorial laboratory experiment, taking into account several factors that have the greatest influence on the process of interaction of working parts with the soil. Virtual simulation methods were applied with use of Computer-Aided Engineering (CAE) FlowVision®(TESIS Group) engineering analysis system, allowing creation of close-to-real controlled conditions. Relationships between the lift angle and the span angle of a duckfoot opener were identified; influence of soil moisture content, speed of working parts and their working depth on draft force input and quality of the formed seedbed was determined with justification of their optimal combination. Presented technology and the planting unit assure the technological process quality, they are of practical value for agricultural and engineering companies, as well as for research institutes for design of modern agricultural machinery.

The work is devoted to the problems of manufacturing thinwalled parts of the aviation industry and instrument engineering on modern numerical control machines. The main reason of defects of such products -loss of dimensional accuracy is revealed. The reason for this is the elastic deformation of the workpiece during milling. A mathematical model for calculating the elastic pressing of a thin wall during milling is proposed. The method of checking the adequacy of the developed model with the help of engineering analysis system is presented. The minimum set of geometrical parameters of the processed element and the cutting tool necessary for search of the rational cutting mode was defined. A new approach to automation of this process present through the evaluation of all possible solutions. The calculation of the rational cutting mode was made taking into account the conditions of rigidity of the workpiece. Conclusions on the efficiency of the developed technique are made.

Simulation Package

The Boeing Engineering Analysis System is a menu-driven simulation package for modelling, analysis and design of large complex dynamical systems. The latest version, EASY5x, also provides multi-layered hierarchical modelling facilities and runs under X Windows. The package has many powerful nonlinear/ linear, continuous/discrete, steady-state analysis and optimization functions. This paper describes an introduction to the facilities and features offered by EASY5x. The modelling, control and optimization of a Coordinate Measuring Machine (CMM) is presented as an industrial example to evaluate some important features of EASY5x.
