Abstract

The previous experience of creating experimental road trains with an active trailer and semi-trailer is analyzed against the background of modern technological capabilities of transport engineering and the logistical needs of modern construction. The expediency of implementing the concept of a road train with an active trailer based on modern electromechanical technologies is shown. The purpose of the study is to increase the energy efficiency of road trains used in construction for transporting long-length objects (beams, piles, bridge trusses, panels, etc.) by using an active trailer link with an electromechanical drive. The study solves the problem of modeling the movement of road trains with passive and active semi-trailers and comparing their energy efficiency and safety indicators. The methods of modeling the movement of cars and road trains, characteristic of the theory of movement of transport vehicles, approaches of theoretical mechanics and applications of differential calculus, applied numerical modeling in the SimuLink environment are used. A mathematical model has been obtained that allows calculating the energy efficiency of a road train when using passive (towed) and active semi-trailers. The cycle of the road train movement has been developed and tested for use in severe road conditions (construction with weak road infrastructure, forest complex, transportation of special cargo). The implementation of the computational model by means of the SimuLink software package is proposed. Based on the simulation results, conclusions are made on the energy efficiency and safety of road trains with an active trailer link with an electromechanical transmission.

带主动式半拖车的混合动力公路列车在公路建设工程中的能源效率

在现代运输工程技术能力和现代建筑物流需求的背景下，分析了以往制造带主动拖车和半拖车的试验性公路列车的经验。结果表明，在现代机电技术的基础上实施带主动拖车的公路列车概念是可行的。研究的目的是通过使用带机电驱动的主动拖车连接，提高建筑工程中用于运输长距离物体（梁、桩、桥桁架、板等）的公路列车的能效。该研究解决了使用被动半挂车和主动半挂车的公路列车运行建模问题，并比较了它们的能效和安全指标。研究采用了汽车和公路列车运动建模方法、运输工具运动理论特点、理论力学方法和微分学应用、SimuLink 环境中的应用数值建模。通过建立数学模型，可以计算出公路列车在使用被动（牵引）和主动半挂车时的能源效率。已开发出公路列车运行周期，并在恶劣的道路条件下（道路基础设施薄弱的建筑、森林综合体、特殊货物运输）进行了测试。建议通过 SimuLink 软件包实施计算模型。根据模拟结果，对带有机电传动主动拖车连接装置的公路列车的能源效率和安全性做出了结论。
