Os'machko O. Models of computer-aided system design of the automatic transmission

Object of research - processes of designing automatic transmission. Research subject - model of system designing automatic transmission and choice of a software for simulation modelling of functioning automatic transmission. The purpose of thesis - increase of efficiency of synthesis automatic transmission at the expense of development of mathematical models of the automated designing automatic transmission and its blocks, system of automatic control and its elements, communications between them, choice of a software for simulation modelling, and also algorithm of simulation model of functioning electromechanical automatic transmission. The methods of research are based on principles of the system analysis and system synthesis for structural of processes of designing automatic transmission and its system of automatic control; methods of mathematical modelling and automated designing, discrete programming, multicriterial of an estimation and optimization for a choice of structure automatic transmission, its blocks, system of automatic control, its elements and communications between them, and also software for simulation modelling synthesized automatic transmission. The results of theoretical researches and developed mathematical models are realized as program-methodical complexes of computer technology of the automated designing. The scientific novelty - for the first time is developed general model of system designing automatic transmission and its decomposition on private tasks, that allows, as against known methods, to structure and system to consider process of designing automatic transmission; The mathematical models of an estimation and choice of structure automatic transmission, its blocks, elements of system of automatic control and communications between them are developed. They allow, as against known models, to accept the design decisions on much functional and cost criteria which are taking into account a degree of uncertainty of the information on their importance. It enables to raise efficiency and efficiency of the accepted decisions; have received the further development methods many criteria of an estimation and optimization by distribution them on a new class of objects - process of system designing automatic transmission. The results thesis were used at designing automatic transmission for a tractor such as KTP-17222 for SE of a Research institute of technology of instrument making. The results thesis are used in educational process of automation and computer-integrated technologies faculty: At teaching lectures, realization of laboratory jobs and course designing on discipline " The automated electric drive "; at teaching lectures, realization of laboratory jobs on discipline " Identification and modelling of technological objects ".
