Darenskiy A. Scientific basis for enhancement of resources of industrial transport based on predicting the state of the "crew - rail track"

A research object is a process of forming of tekhniс-ekonomical indexes of functioning of hauling rolling stock. During the study, we used the following research methods: analytical methods of theoretical and structural mechanics using theoretical spatial models for developing general method for determining the interaction forces of rolling stock and track; finite element method - to calculate and analyze the spatial stress-strained state of the upper track structure; methods experimental studies of the elements of the upper track structure. The thesis contains theoretical bases and methodological positions for determination of technical and economic indicators of traction rolling stock functioning taking into account life cycle according to service conditions, operating repair and maintenance service systems. On the basis of cycle components classification and estimation, the scientific approach was created which allows substantiating the expediency and profitability of projects for railway machinery updating taking into account possible changes in its condition during this period.
