Based on the analysis of the methods for arranging automatic block signal system and signal signs of automatic train control, used as an independent signaling and communication device during train movement, it has been proved that determining the lengths of block sections at specified train-to-train and intervals reduces the carrying capacity of the hauls. It has been established that a significant increase in the working capacity of the hauls is achieved when determining the lengths of “fixed” block sections by calculating the maximum stopping distances of trains on each haul, and the lengths of the “running” blocks - on the basis of the operatively calcu- lated stopping distances of each ride, passing along the given section. Particular attention is paid to the application of the cognitive (research) method of using the knowledge and experience of interacting railway transport specialists in the field of creation, design and operation of the systems for interval control of train traffic. The directions of development of software for existing and created information systems that serve graphists-technologists, field dispatchers and machinists have been determined. It is shown that the use of the method of simulation modeling of train movement links the times of arrival and departure of trains with the beginning and end of station technological operations, which expands the possibilities of taking into account the influence of technical and organizational factors on the assessment of the working capacity and processing capacity of train stations. It is proposed to supplement the software of the method with a set of algorithms that determine the required working capacity of railway lines, stations, sections, lines and directions for a given number of trains of various high-speed categories, taking into account the prospect of providing possessions for repair work, de- pending on the planned volumes transportation.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133082614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For conformity assessment of such critical safety related rolling stock component as axle-box bearings the supporting standard GOST 32769–2014 (or GOST 18572–2014) is used. For traditional and high-speed rolling stock the standard foresees changing of the single run duration in the course of full-scale bench tests of axle-box bearings for determination of certification parameter. The example of the test runs of a high-speed train showed that during the time of such single run (in accordance with the standard) the axle-box bearings fail to reach the maxi- mum values of the certification parameters, which can result in unreliable conformity assessment of the axle-box bearings with the safety requirements. With the purpose to increase the reliability of the assessment of the maximum temperature of the axle-box bearings for traditional and high-speed rolling stock and also to bring the conditions of the bench tests of axle-box bearings to the full-scale operating conditions as possible, we propose to consider in the supporting standard the possibility of upholding the duration of single runs while conducting bench tests unchanged, independent of the design speed of the rolling stock","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122555507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need to solve the problems is due to the requirement of a qualitative improvement in the reliability of receiving codes, and as a consequence, the capacity of existing lines. First of all, this refers to a significant increase in the quality of reception and processing of information flows from rail lines. Today it is difficult to imagine the organization of the movement of rolling stock without relying on automatic block systems with secondary sealing of tonal track circuits by frequency modulation signals or automatic cab signaling without the use of multivalued automatic cab signaling with phase-difference modulation. Taking into account the objective fact of noise emission from the operation of energy-intensive railway equipment and modern locomotives, the issues of reliability and noise immunity of receiving discrete information (including signals of traditional automatic cab signaling) are becoming more and more urgent. Analysis of the reasons for the decrease in the reliability and noise immunity of railway automation and telemechanics systems, and, consequently, traffic safety also comes to the fore.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131833737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article raises complex problems and investigates theoretical provisions of the problems of functioning of low-density railway lines and their interaction with intensive and projected (modernized) lines. The solution to this problem is of great socio-economic and economic importance for the operation of the railway transport network, ensuring the needs of production and the population in transportation. The article proposes a comprehensive synergetic-indicator approach to the management of intensive and low-density railway lines based on existing management functions, including analysis, organization, stimulation, control and coordination of the transportation process. A general assessment of the dynamics of the functioning of low-density railway lines is given. The conceptual structure of the integrated synergetic-indicator approach is presented, which has empirical foundations, prerequisites, theoretical foundations and implementation, confirmed by reliability criteria. The structure of the proposed railway transport management system is developed for the selection of management objects. The elements of interaction of busy, low-density and projected railway lines are established. The mathematical model diagram of the interaction of intensive modernized low-density lines and the state function of the system under consideration have been developed. The modeled transport system is classified.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114766939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The necessity of applying an analytical approach to assessing the stress-strain state of a structure at the initial stages of design and technical operation has been substantiated. The drawbacks of the existing analytical approach to stress assessment are shown. Taking into account the available resources, an acceptable research program was developed and implemented, which would lead to satisfactory results. In accordance with the program, a series of numerical experiments was carried out using software that makes it possible to simulate complex structures and solve them using the finite element method, aimed at obtaining an array of data, the use of which would improve the accuracy of the existing analytical solution. By using software aimed at processing scientific data arrays, mathematical dependences of the required parameters on the initial constructive data were obtained. Formulas and initial data were obtained for calculating correction factors, which improve the accuracy of calculating local compressive and bending stresses. These formulas were combined with the already existing analytical dependencies in order to obtain a simple and easily applicable method for determining the actual local stresses from the application of an indirect concentrated load. As a result of scientific research, a new method for the analytical determination of local bending and compression stresses in riding beams was proposed on the basis of an analysis of the existing methodology and a series of numerical experiments.","PeriodicalId":217313,"journal":{"name":"Automation on transport","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123109903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sys- tem is based on the use of radio frequency identifiers (RFID-tags) to determine the coordinates of the location of the rolling stock and assumes work on principles different from those currently existing. So, the principle of overlapping traffic lights allows the movement of trains of non-standard formations (armored trains, trains with cover platforms, etc.). A special approach to the organization of protective sections behind the tail of a moving train is considered. The proposed technology is a special system aimed at solving a certain range of wartime tasks, therefore, it uses a two-digit signaling (prohibiting movement red signal, permitting movement green signal). This feature is due to the need to ensure the maximum simplicity of this technical tool, the possibility of rapid deployment and short-term recovery.
