“…Feedback is usually carried out according to the signals of the wheel speed sensors of the sides, or according to the signals from thermal accelerometers. In the Russian Federation, a number of technical solutions have been proposed to create alternative kinematic schemes and ensure the control of such controlled PDMs, and approaches to the design and production of such mechanisms have been described (works [15][16][17][18] and others).…”

“…Cross-wheel controlled PDMs are used mainly in transmissions of passenger cars, not necessarily all-wheel drive. There are works in which it is proposed to adapt a controlled PDM to work as part of the transmission of a tractor and other transport and traction machines, including skidders and forwarders, typical for the timber industry (see [15][16][17][18] and others).…”

The article analyzes the experience of using gear controlled power distribution mechanisms in transport engineering as part of a dynamic stabilization system for high-speed ground vehicles. An overview of the sources on this issue is given. It is shown that the issue of increasing the lateral stability against skidding is relevant in modern conditions and has received a mathematical description mainly in the application to passenger cars. Attention is paid to theoretical studies of Russian scientists involved in the problem of power distribution control in transmissions of transport vehicles and tractors for various purposes. A solution to the problem of full control over the distribution of torques in a transmission containing several drive axles is proposed in the form of a structural diagram of a transmission based on the use of controlled gear power distribution mechanisms. The considered solutions are applicable for monohull vehicles and road trains with an active trailer link. Methods for determining external parameters (gamma of gear ratios) for interaxle and interwheel controlled power distribution mechanisms are proposed in the application to the case of turning a road train with an active trailer-dissolution having an electromechanical transmission.

“…So on modern transport tracked vehicles (TTV), when moving at a maximum speed, about 50% of the power developed by the engine is lost precisely in the propulsion unit. It is possible to reduce these losses by observing the principles of optimal design [1,2] and optimal track tension.…”

The article proposes a method for calculating the static position of the machine body. The mathematical model of the running gear is given. The dependence of the position of the center of mass in height relative to the ground on the pre-tension forces, as well as the angular deviation of the longitudinal axis of the hull from the horizontal position, is shown. A control calculation was performed, the results of which are presented in the form of graphical dependencies. The numerical experiment was carried out on the example of a tracked vehicle of a light category with a rear drive wheel.

“…Several previous studies that have been carried out in frame analysis are testing vibrational characteristics and optimizing the frame of corn harvesters using the modal analysis method [11,12], the study of frame fatigue life [13,14], the effect of cracks on the dynamic characteristics of frames [15], corn harvester frame optimization design based on reliability analysis [16], frame design and specification as a passive safety feature [17], multi-section frame for extreme terrain [18]. Many aspects must be considered in planning the frame design, such as the selection of the type of frame, the selection of profiles, the selection of materials, the safety factor [19], and the machining and assembly processes.…”

The extent of existing corn land in Indonesia and the activities carried out by farmers in corn farming requires the innovation of an effective and efficient corn harvesting machine. This underlies the Research Center for Appropriate Technology located at the Faculty of Engineering, Universitas Negeri Padang to design a corn harvesting tractor that can facilitate the community in carrying out activities in the agricultural sector. The design of the corn harvester tractor consists of the harvester mechanism, the frame, the engine, and the powertrain. The frame is a crucial component of the corn harvester tractor, and its strength depends on its shape and proportions. The construction's strength of the frame must take into account both safety considerations and the structure's strength. The purpose of this study is to evaluate the frame strength of a corn harvester tractor made of steel of the ASTM A36 type. In this study, the von Mises stress that exists in the frame is used to calculate the strength of the frame of a corn harvester tractor. In numerical analysis, the chassis utilizes two tests with various load variations, namely the concentrated load and the load that is evenly distributed on the surface. The simulation results show that the frame of the corn harvester tractor can withstand the load well. The results of the stress analysis that occurs on the frame of the corn harvester tractor are that the maximum stress that occurs due to the concentrated load on the frame is 3.248 MPa. While the maximum stress that occurs due to the distributed load acting on the frame is 3.510 MPa. In addition, information was obtained that the value of the safety factor for the frame with ASTM A36 type met the component requirements that could withstand concentrated loads and distributed loads
