Kokhanenko V. The Elaboration of the Technique for the Diagnostics of Internal Damages of Tires During Maintenance

Object of research: process of interaction of the trunk with road to operation and increase of a level of traffic safety of transport with pneumatic trunks. The purpose of research: will consist in creation of a quality monitoring and means of diagnosing of a technical condition of automobile trunks in operation. Methods of research: scientific methods of physical and mathematical modeling, the theory of planning of experiment, probability theory and mathematical statistics. Theoretical and practical results: modeling defect of the trunk as a cut is executed and calculations of it is intense - deformed conditions and heat buildups in the field of defect, the opportunity of an estimation of the sizes of internal defects of the trunk on values of superficial temperature fields of the trunk is determined; the method of an estimation of a residual resource of the trunk by criterion of development of defect till the critical size is proved; Techniques of diagnosing of presence of latent defects in the trunk. A new manufacturing application: dependences of influence of internal defects on intense - deformed a condition of the trunk and its temperature fields are determined; for the first time carry out modeling of defect of the trunk as a cut is executed; methods of an estimation of the sizes of internal defects and places of their arrangement in the trunk on values of its{her} superficial temperature fields, and also a method of an estimation of a residual resource of the trunk by criterion of development of defect up to critical value are experimentally proved. Degree of introduction: recommendations and technical decisions are used at designing trunks in Open Society " Rosava ", and the technique of diagnosing of presence of a latent defect in the trunk on values of temperature fields on its her external surface is introduced in "Belocerkovsk" trolleybus management and in group of technical service GU of the Ministry of Emergency Measures of Ukraine in the Kharkov area.
