Abstract
The article substantiates the relevance of off-road container transportation by ground railless transport vehicles and weight-size parameters of the transported cargo for the mining operations. A hierarchy of complex mobility properties is developed to investigate the significance of performance properties, which is divided into levels of properties. Taking into account the hierarchy of properties, the measuring instruments are determined, the indicators of which can be used to determine the priority technical solution for container and rock transportation vehicles. The article provides a classification of tracked vehicles and tracked trains with the analysis of their design and layout variants. As a result, variants of the concepts of vehicles for off-road container and rock transportation have been formed. Based on the analysis of the hierarchy of performance properties, design and layout variants of modern tracked vehicles and considering the selected objects of research, the conceptual design of a semi-trailer tracked train and a tracked train with a double-hinge fifth wheel coupling has been proposed.
Highlights
The container traffic is increasing every year worldwide, new terminal infrastructure facilities are being built to handle sea and rail transport in order to deliver containerized goods to the remote end user
Depending on the functional purpose of the vehicle, when assessing the effectiveness of the adopted technical solutions, a certain set of the most important properties, the significance of which is determined by operating conditions, must be considered
The work [2] gives the dependences reflecting the expedient scope of application of various ground railless vehicles with due regard to their gross weight and ground carrying capacity. Analyzing these dependences we established that a radical increase in the crosscountry mobility of vehicles for off-road container transportation can only be achieved by using tracked vehicles or combinations of several tracked vehicles
Summary
The container traffic is increasing every year worldwide, new terminal infrastructure facilities are being built to handle sea and rail transport in order to deliver containerized goods to the remote end user. The standard containers are used for freight transportation: 20, 40- and 45-footer containers conforming to the international standard ISO 668:1995 (GOST R 53350-2009). Kg Transportation of containers using a single multipurpose high mobility vehicle which can transport both one 45-foot container and two 20-foot containers at the same time is the most economically feasible option. These containers can be transported off-road using high mobility vehicles with a payload capacity determined by
