Baranovskiy D. Development of scientific bases of increase of longevity of diesels of the special self-propelled mobile composition of railways

Dissertation is devoted to the questions of development of scientific bases of rise of longevity of diesels of the special self-propelled mobile composition of railways. In dissertation the results of researches of capacity, efficiency of exploitation and longevity of diesels of the special self-propelled mobile composition railways are resulted. The mathematical design of longevity of diesels is conducted on the basis of synergetic principle with the use of thermodynamics aspect. A model for prognostication of longevity of diesels on the basis of synergetic approach and kinetic conception of destruction of the tribosystems materials, which takes into account the indexes of faultless, system of technical service and repair and terms of work of the special self-propelled mobile composition railways, applications of different technological methods of rise of longevity and processes of burn-in in tribosystems, is got. A model includes expression for prognostication of remaining resource of diesels at presence of data about their technical state, passing of processes of independent organization in tribosystems and from distributing of time of their work; and also dependences of intensity of wear of the tribosystems diesels taking into account operating factors at the use of different methods of rise of their longevity which allows to choose a rational technological method for the proper external environments of the special self-propelled mobile composition railways at providing of the lowest value of intensity of the tribosystems wear.
