A mathematical model of the heat transfer during grain drying has been developed. To estimate qualitative parameters of a technological process, the theory of the tolerance control is used. Control criteria for the drying process in rhomb-shaped aggregates have been determined. The obtained results allow increasing the technological reliability of grain dryers operation.
A model of a machine operation with account for systematically important factors has been proposed. It is dealt with practical methods for quality assessment of agricultural machinery and its technological processes.
The obtained results afford evaluation of the Forage Shredder technological reliability during its operation as component of a flow line.
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.
