Babicheva O. Increase of the pneumatic tires' resources of travel facilities

Object of research: is the resource of pneumatics of transport vehicle. The purpose of research: rise of resource of pneumatics of transport vehicles due to development of effective methods of improvement of their exploitation and scientifically grounded decisions in area of constructing of tires and technology of making of reinforcing element. Methods of research: method of theory of Dimensions, graphic and analytical method with the use of modern mathematical vehicle and COMPUTER, modern methods of researches in industrial terms with the use of different facilities of measuring technique, analysis of authenticity of the got results confirmed by experimental-industrial verification and comparison with the real data of run of tires of transport vehicle, methods of mathematical statistics, theories of reliability, informatics. Theoretical and practical results: the offered dependence for determination and estimation of resource of tires enables to define a run with the high degree of authenticity, thatis confirmed on the example of enterprises of the "Gorelektrotrans" of city Kharkov; the developed method of determination of resource of tires of transport of a different setting allows to take into account intensity of exploitation, state of road-climatic terms, degree of chemical contamination, and also influencing of the state of reinforcing element on their longevity; developed nomogramma from determination of resource of tires allow to carry out the choice of the optimum modes of their loading and estimate the term of service of tires for concrete external environments; the recommended optimum parameters of tuning of mechanism of false twist provide the receipt of rectilinear metal cord with the minimum remaining twist at the level of world standards. Novelty of the got results: a new conformity to the law of change of factors affecting the resource of tires taking into account high-quality description of reinforcing element is set; intercommunication between operating factors and high-quality description of metal cord is exposed, and also their influence on the resource of tires; the change of remaining is first definite the twisted reinforcing element of the type 9Л15/27 from the row of factors taking into account tuning of parameters of mechanism of false twisted of wring, high-quality indexes of the finished product and initial material. Degree of introduction: the results of researches are realized on the state enterprise of the "Gorelektrotrans" of city Kharkov, in a bus factory and trolleybus management of the city White Church , and also in the educational process of the Kharkov national academy of city economy at preparation of young specialists. Sphere of the use: transport enterprises of communal economy.
