摘要

创造有前途的技术手段的过程总是基于先前研究的结果,这些研究致力于对正在开发的样品的技术要求进行定义和论证。在研究工作阶段使用现代模拟(计算机)建模方法有助于分析开发系统的许多可用选项,评估其单个元素的负载程度,形成功能和组成方法的合理建议。本文描述了应用仿真建模方法的一种方法,该方法的开发是为了评估由于轨道电车的数量变化而获得的效果,这些电车用于将轨道网格的链路馈送到其铺设的地方。根据一种有发展前景的门式拖拉机铺地机的战术技术特点进行了评价。仿真结果为轨栅铺设过程中各项时间指标的统计数据。开发的仿真模型可以在研究工作阶段计算单个技术周期的生产时间,该阶段致力于创造移动铺设铁路轨道的手段,在缺乏初始数据和用真实物体进行全面实验的复杂性的情况下。分析生产设施的利用程度,从数学上确定运输工具的最优数量,以减少装载和铺设轨道工程中涉及的技术手段的停机时间。作为初步资料,以PB-5拖拉机铺轨机、PT-13轨道轨道车、汽车和气动轮式车辆在轨道上放置的通用装置为主要技术特点。所研究的生产过程是根据“轨道工作技术图集”中所列的“按环节铺设轨道面板”技术图,根据已接受的工作组织和技术方案进行建模的。所开发的模型可以作为与组织相关的多节点、多通道交通建设编队功能模型的统计数据来源,其中包括系统功能的几个级别的表示。

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.
