“…Regarding manned trucks, the analysis is related to different position configurations of the motorization system on the hub of the front or rear wheels [44] and to the positioning of the battery pack in the frontal or posterior region of the vehicle chassis, with the objective of improving the comfort of the driver [52]. As for the application in unmanned trucks, the traction and energy regeneration system consists of two electric motors, one for the traction of the front axle and the other for the rear axle, with the objective of evaluating the energy consumption in relation to trucks with a system of traditional transmission and an internal combustion engine [53].…”

This article presents an original research methodology that combines insights from patents and academic research, offering a unique perspective on energy recovery technologies for trucks equipped with refrigeration units. The purpose of the study is to perform a functional analysis of existing solutions and to suggest a mechanism for exposing unexplored areas and opportunities for innovation. To achieve this goal, a systematic opportunity scan is presented, investigating patents and conducting a state-of-the-art search of existing technologies. This scan classifies a diverse range of solutions, elucidating their interconnections and providing an overview of the existing technological area, covering system components and technical trends. Thus, the main functions and components are listed, as well as the system requirements. Once the functions have been surveyed, a morphological matrix is proposed, and five main functions are analyzed. This methodology makes it possible to list the majority of the possible solutions for the functions analyzed, taking into account the components observed in the literature review and patents, including new components raised by the research group. Finally, with the morphological matrix structure, it was possible to combine unexplored elements, achieving innovative solutions.

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.

“…Two-flow stepless hydraulic-mechanical transmissions are mainly used on tractors [1] and mine diesel locomotives [2] with a small engine power. However, for quarry dump trucks [5,6] the system of storing electrical energy in largecapacity capacitors in braking modes (regenerative braking) with its subsequent use in acceleration and traction modes is quite effective, as well as the storage of electrical energy can be additionally carried out during operation of the diesel generator set in idle mode.…”

Purpose. Substantiation of peculiarities of modernization of a heavy-duty vehicle with a hybrid power transmission by using the formed set of analytical and technological solutions for power transmission under operating conditions. Methodology. For the developed functional model of a hybrid vehicle operation, the parameters of the functional model and its links are presented, the relationships between the elements are described, and the boundary conditions are formed. A combined series-parallel hybrid drive scheme has been used, as it has a higher efficiency compared to parallel and series ones. When operating in idle mode and low loads, the diesel generator set replenishes the energy reserve in the energy storage device and the vehicle is operated. To recharge the energy storage devices, it is possible to use the traction electric motor as a generator, and during operation it is used in the energy recovery mode during vehicle braking. An optimization mathematical model has been developed to determine the parameters of the power plant and energy storage device, taking into account operating conditions. A procedure has been developed along with, on its basis, a subroutine algorithm for calculating the required energy intensity of the energy storage device and the power of the vehicle’s power plant. An assessment of the modernization effectiveness of mining dump trucks by hybrid power transmission was made. Findings. A functional model of a hybrid vehicle operation under appropriate operating conditions has been developed, and the main parameters limitations of the state have been given. The corresponding procedures and algorithm for calculating the parameters of the energy storage device and the power unit were compiled and then were used in the corresponding computer calculation program. In the study on fuel efficiency, three BelAZ-7547 dump trucks were considered. The values of the kinetic energy configuration were determined with an increase in speed (acceleration) and with a decrease in speed (deceleration). An assessment of the upgrading effectiveness was made for mining trucks with hybrid power transmission. The payback period of the corresponding measures was 1.42 years. Originality. To determine the power storage and power unit parameters, a functional model of a hybrid vehicle operation and an optimization mathematical model for determining the parameters of the power plant and energy storage, taking into account operating conditions, have been developed. The substantiation of a complex of analytical and technological solutions for the power transmission of a hybrid mining dump truck under operating conditions has been carried out. Practical value. The results obtained are useful in the implementation of the modernization of heavy mining dump trucks with hybrid power transmission in the operating conditions.
