Published: April 2022

A description of the unique scientific facility “Injection” for experimental investigations of the dynamics development of fuel torches under various conditions of injection into a constant-volume chamber is given. The facility is equipped with the Common Rail fuel systems with adjustable fuel pressure, compressed air supply from the cylinder, scavenging of the constant volume chamber, control of the bench, registration of control pulses, and high-speed video recording of processes inside the chamber. With the help of the controller-synchronizer, the moments of the beginning and the end of the electric pulse of the electromagnetic nozzle were controlled, simultaneous video recording of the Photron FASTCAM SA-X2 color high-speed video camera and the recording of oscillograms on a Tektronix TDS-2014C digital oscilloscope. The duration of the control electric pulse of the nozzle was set from 0,5 ms to 3,0 ms. The pressure in the fuel rail was set from 100 MPa to 165 MPa. The actual moments of the beginning and the end of the fuel injection were determined by the results of the video shooting and counted from its start. The delays of the beginning and the end of injection were determined by comparison the results of video-recording with recording the control electric pulses of fuel nozzle on the oscilloscope. The dynamics of the change in the length and angle of the cone of fuel torches were determined by measuring the contours of the visible parts of the fuel torches on the photorecordings. The delays in the beginning and end of fuel injection were practically 0,3 ms and 1,0 ms, respectively, at all the investigated modes. As a result the duration of the fuel injection process as a rule by 0,7 ms exceeded the duration of the control pulse. At the beginning of injection during 0,5 ms the velocity of the vertices motion of the fuel torches was 35…50 m/s, depending on the pressure, then it decreased to 31…38 m/s. It has been established that when the pressure in the fuel rail increases from 100 MPa to 165 MPa, the angles of cones of fuel torches decrease from 20º…22º to 17,5º…18,5º, that is, on average by 15%.

Published: April 2022

The issues of application of electric drives (ED) on mobile energy and transport and technological agricultural means are actively discussed for the last 10-15 years in the agroengineering community. This is a very urgent and energy-efficient event for the further improvement of agricultural machinery. The urgency and importance of this work is related to the fact that it is also proposed to transfer active working bodies of agricultural machinery to ED. The various aspects related to the use of automated and robotic ED on agricultural machinery are considered in this paper. Various advantages of ED use have been identified - economic, ecological, technical, functional, etc. The design features of some existing mobile agricultural machines on automated ED have been analyzed, various layout electrical schemes such as the application of the Diesel-Generator system, autonomous power sources and hybrid power plants have been considered. Dynamics of development of technical and economic indicators of the component base used in automated ED such as-electric machines, converter equipment, storage batteries and etc. is given. Conceptual schemes of creation of basic mobile platforms based on automated ED have been substantiated which have two schemes of typical layouts: the application of the Diesel Generator system and the Autonomous Battery System, taking into account the functional and operational requirements for these mobile platforms. The main aspects of design, research and production of modern domestic automated ED’s, including problem aspects are revealed. In this article authors considered the prospects for using constructively and technologically advanced electrochemical energy sources such as fuel cells, as an energy installation for ED.

Research and development in the field of driver assistance systems (ADAS) is being carried out to reduce the number of road accidents and improve road safety. Nowadays ADAS systems are widely spread, for example lane support assistant, obstacle detection on the lane, road signs, parking assistant, pedestrian identification system, night vision system, adaptive cruise control, blind zone monitoring system, etc. Driver assistance systems, which are developed by many large foreign vehicle manufacturers, have already been introduced serially and are being actively used on public roads. However, in the Russian Federation market there are practically no own developments and solutions, which can be installed in series on automobiles. The installation of foreign ADAS systems on domestic vehicles is difficult due to differing operating conditions, some differences in the types of road infrastructure, and also due to the high cost associated with the unstable economic situation. To implement the functions of ADAS on commercial vehicles, adapted to the conditions of operation in Russia, the team of Nizhny Novgorod State Technical University n.a. R. Alekseev together with the GAZ Group are working on the concept of a driver assistance system with the possibility of adjusting the movement of the automobile through integration into the steering system. The functional and hardware composition of the system is developed. Tests of individual components of the system were carried out in the part of recognizing traffic signs, determining and warning the driver about leaving the lane and about a possible collision with obstacles on the route. Integration of the driver assistance system with steering was carried out by means of data transfer via the CAN-bus of the vehicle. Based on the results of the tests, relevant conclusions were drawn about the efficiency of individual parts of the system and further goals were set for further development and improvement of the driver assistance system that promotes road safety and reduces the number of road accidents.
Problems of finding the best solutions to ensure the passive safety of the cabins of trucks at a minimum weight
Authors: Goncharov R. B , Zuzov V. N
Published: April 2022

This paper considered the main problems of finding the optimal parameters of a truck cabin based on parametric and topological optimization in order to meet the requirements for passive safety according to international rules and obtain its minimum mass. The article presents the developed rational finite element models (FEM) of the cabin and the pendulum for optimization problems, allowing to obtain results with acceptable accuracy and minimal solution time when using the LS-OPT and LS-TaSC programs with the LS-DYNA solver. Steel lining and foam aluminum filler are used as cabin reinforcement elements. To solve the problem and more fully assess the effect of the parameters, several options for cabin refinement were considered. Topological optimization was carried out with the aim of obtaining a picture of the best distribution of the filler along the cabin frame. Parametric optimization was carried out by selection of the properties of the filler (aluminum foam) and the thickness of the structural elements of the cabin. In addition to optimization, the sensitivity of the design to the variation of variable parameters was investigated in order to identify the degree of influence on the optimization result. Since the duration of the solution is very high (up to several days on available computers), an approach was developed based on the studies that were carried out, which at various stages reduced the number of variables and, thus, reduced the solution time. As a result, it was ensured that the requirements for passive safety were satisfied (these requirements were not met before optimization) with optimal mass distribution as a result of the combined use of linings and filler. The increase in cabin weight was 20%. The use of linings only allowed to meet the rules for passive safety, but gave an even greater increase in the weight of the cabin.

Published: April 2022

The results of tests of various types of caterpillars on the tractor VT-150 on the evaluation of traction indicators, as well as sealing effect on the soil are presented. It is established that the tractor BT-150 with rubber-reinforced caterpillars in the zone of nominal traction effort of 36 ... 45 kN for tractors of class 3 develops the maximum traction power of 90.5 kW at a speed of 8.1 km / h, tractive effort of 40.2 kN and slipping 5, 1%, which is at the level of the corresponding indicators of the tractor with metal caterpillars with open metal joint. An assessment of the parameters of the effect of propulsors with different types of caterpillars on soil was carried out at the North Caucasus Experimental Station of the Krasnodar Research Institute of Agriculture of the Russian Agricultural Academy of the Russian Federation in an indoor sand channel. As a result, it is established that rubber-reinforced caterpillars ensure the operation of the tractor with soil moisture up to 0.7 НВ in the spring period and up to 0.9 НВ in the summer-autumn period. The analysis of the test results of the VT-150 tractor with various caterpillar designs showed that the use of rubber-reinforced caterpillars on the machine ensures: equality of traction parameters, including efficiency, machines on rubber-reinforced caterpillars and on metal caterpillars with open metal joint in the zone of nominal tractive effort for tractors of Class 3; the possibility of the machine working the field in conditions of high humidity; the ability of the machine to travel on roads with hard and advanced coatings without destroying them in comparison with metal caterpillars with open metal joint. It is shown that caterpillars with rubber-reinforced caterpillars have advantages in durability in comparison with metal caterpillars with open metal joint both on tractors and on combines.
Experimental verification of the reliability of the method of designing driving wheels of pin gearing with rubber-reinforced caterpillars

Published: April 2022

The obvious advantages of rubber-reinforced caterpillars over tracks of other types make them indispensable for traction and transport vehicles for various purposes. Among other things, such caterpillars are distinguished by the possibility of their installation on the machine in place of metal caterpillars without a significant alteration of the design of chassis. Nevertheless, together with the replacement of the metal caterpillar with rubber reinforced in practice, it is also necessary to replace the existing driving wheel with a specially designed for rubber-reinforced caterpillar. This happens due to the fundamental differences in caterpillar designs and the features of their work. Until recently, there was no unified engineering method for designing the engagement of the driving wheel with the rubber-reinforced caterpillar. In one of the previous works, the authors developed a technique that takes into account the features of rubber-reinforced caterpillars. This article describes the experimental testing of this technique on the example of a specific machine - self-propelled tracked sprayer for agricultural purposes. Designed in accordance with the developed technique, prototypes of driving wheels in the self-propelled caterpillar sprayer passed a complex of factory tests, including static and dynamic phases. At the static phase of the tests, the input and output of the teeth of the drive wheels were checked from engagement during the assembly of the drive system of the chassis. During the dynamic phase, the reliability of the engagement has been checked at various driving regimes and loads of the self-propelled caterpillar sprayer. In addition, a study was made of the engagement in dynamics with the hung side of the chassis. Experimental studies have confirmed the reliability of the driving wheel samples, the reliability and adequacy of the developed methodology. The recommendations for further investigation of the pin gearing and refinement of the design methodology are given in the paper, including the creation of specialized bench equipment.

Modeling of the processes of evaporation and mixture formation in the cylinder of a tractor diesel engine when working on an ethanol-fuel emulsion
Authors: Likhanov V. A , Lopatin O. P , Chuprakov A. I , Yunusov G. S
Published: April 2022

The article is devoted to the problems of modeling the processes of evaporation and mixture formation in the cylinder of a tractor diesel 4Ch 11.0 / 12.5 with a combustion chamber of the TsNIID (Central Research Diesel Institute) type when working on ethanol-fuel emulsion. In a diesel engine 4Ch 11.0 / 12.5 with a combustion chamber of the TsNIIDI type, when working on an ethanol-fuel emulsion, a volume-film mixture takes place with the predominance of evaporation of the fuel prior to the start of the combustion process. The evaporation of fuel depends not only on the dynamics of the motion of the medium and the temperature conditions, but also on the characteristics of injection and spraying. The speed and turbulence of the mixture are important characteristics. Therefore, the above parameters determine the intensity of evaporation and mixture formation. During the evaporation of droplets of ethanol-fuel emulsion and diffusion into the surrounding vapor-air medium, a combustible mixture forms. It does not ignite the fuel itself, but its vapor mixes with air. The constructed model takes into account the peculiarities of evaporation and mixture formation during the spraying of fuel and allows us to accurately calculate their speed. In regions where the concentration of droplets is low, calculations are made for one drop, and in zones with a high concentration, the interaction between the drops during evaporation and combustion is taken into account. In order to better understand the nature of the interaction of droplets with each other and with the surrounding turbulent gas flow, the entire combustion process is divided into stages: the formation of aerosol particles, the movement of droplets, their evaporation, mixing with the oxidant, ignition and combustion. The following basic assumptions are also accepted: there is a spherical symmetry of drops; The thermal conductivity coefficient, the specific heat are constant and do not depend on temperature; there is an identity of heat and mass transfer processes; the quasistationary nature of the process takes place.
