Simulation modeling of the process of transportation of track panels on track railway trolleys
The process of creating promising technical means is always based on the results of previous studies devoted to the definition and justification of the technical requirements for the samples being developed. The use of modern methods of simulation (computer) modeling at the stage of research works helps to analyze the many available options for the implementation of the developed systems, assess the degree of load on their individual elements, form reasonable proposals for the methods of functioning and composition. The article describes one of the ways of applying the simulation modeling method, developed in order to assess the effect obtained due to a change in the number of track railway trolleys used to feed the links of the rail grid to the place of their laying. The assessment is carried out on the basis of the tactical and technical characteristics of a promising portal tractor track-laying machine. The result of the simulation is the statistical data of the time indicators of the process of laying the rail grating. The developed simulation model makes it possible to calculate the production time of individual technological cycles at the stage of research work devoted to the creation of mobile means for laying railway tracks, in conditions of a shortage of initial data and the complexity of conducting a full-scale experiment with real objects. To analyze the degree of utilization of production facilities and mathematically substantiate the optimal number of transportation means involved, in order to reduce the downtime of technical means involved in loading and track laying works. As initial data, the main technical characteristics of the promising PB-5 tractor track-laying machine, PT-13 track railway trolleys, universal devices for placing automotive and pneumatic wheeled vehicles on the railway track are taken. The production process under study was modeled based on the accepted options for the organization and technology of work according to the technological map “Laying a track panels by links” included in the “Collection of technological maps of track work”. The developed model can act as a source of statistical data for organizationally related multi-node, multi-channel models of the functioning of transport construction formations, which include several levels of representation of the functioning of the system.
