Kryvoshapov S. The research of method and means of general diagnostic of the automobile on change of efficiency

The object of a research: automobile, stand with racing drums and means of diagnostics. The purpose of research: theoretical and experimental substantiation of methods of diagnosing of availability index of product automobiles on a power index: EFFICIENCY of the automobile. Methods of research: fundamentals of mechanics and thermodynamics. Equipment - control measuring, analog-digital converter and personal computer. Theoretical and practical outcomes: the mathematical model of the definition the EFFICIENCY of the automobile on a road and on the stand with racing drums permitting exacter to calculate economic and power indexes of the rolling-stock is developed which as against existing more completely takes into account operation both design data of the automobile and stand; the mathematical model of the definition of techical and economic EFFICIENCY permitting is developed to produce an evaluation of an overall performance of the rolling-stock in view of it of a construction, availability index of pro duct and conditions of maintenance; the new performances of an assotiation of a modification of EFFICIENCY of the automobile from availability index of product of systems of a drive, transmission, suspension bracket and sprockets are obtained; the new technique and algorithm of common diagnosing of a drive, transmission, suspension bracket and sprockets on a power criterion on the stand with racing drums is developed; The technique of the definition of mechanical losses in a drive, transmission and sprockets on "shall run out" with reference to the stand with racing drums is developed; is developed and the new measuring system based on use analog-digital converter and personal computer is applied. Degree of application - on the mobile diagnostic server "Mobile Diagnostics server of cars" (Kharkov) and State automobile inspection, in the automobile transport firm of number 16356 and the automobile transport firm of number 16364 (Kharkov). Orb of use - motor transport.
