    Machines. Technologies. Materials., Vol. 12 (2018), Issue 1, pg(s) 28-30

    Abstract: Management is the process of processing the information aiming decision making to resolve problem or to achieve the target. High advanced automated processes, including the vacuum system with pump and pressure control, management of the cooling system, management of the manipulator, high voltage control and emission current, the control of the electron beam movement and its characteristics, as well as computer-based automatic control ofthe beam power distribution, must be integrated on the basis of the use of systems for operational management of production. The present work presents the hierarchical structure and architectural framework for the management of an installation for electron beam welding, evaporation and surface modification.

  • THE EFFICIENCY OF AUTOMOTIVE VEHICLES BASED ON INTELLIGENT ONBOARD SYSTEMS

    Broad automotive engineering in modern agricultural technologies results in the need to improve the operational characteristics of internal combustion engines. In this regard, the internal combustion engines are increasingly stringent requirements in terms of energy conservation and environmental safety. Improving the efficiency of operation of the engine is reduced to the complex optimization of the main variables and parameters of motors with absolute quality assessment used in these fuels. For a comprehensive optimization should be linked all the characteristics of the engine through certain values and parameters.

    When using fuels of different quality formulated problem is modeled as a multiobjective multi-parameter optimization. One way to solve this problem is the application of the guideline systematic approach – the principles of hierarchy. Management of automotive equipment by using on-Board devices, the functioning of which is considered at the level of subsystems of the engine. The basis for the partitioning of the engine on the levels is the structure, the relationship between the elements and features of their functioning.

    The interaction of the subsystems is reduced to the implementation of vehicle specified performance properties of the command signals from the electronic engine control systems. Decomposition of the hierarchical structure of the engine should be limited to three levels.
    During the development of the automated engine management system used in the dynamic system of the engine as the control objects, simulation, mathematical optimization techniques, special simulation setup and debug systems. In the result, we developed several technical solutions: automated system bench testing of engines and simulation of dynamic stand electronic control systems for internal combustion engines.
