A shortage of class 2 and class 3 tractors was observed in peasant farms. As a solution to this problem, it was proposed to develop a technological module that would increase the versatility of class 1.4 tractors by transferring them to a higher traction class. (Research purpose) The authors aimed to substantiate the nominal operating power of the engine for a tractor with a technological module. (Materials and methods) To calculate the required power, the authors proposed a method that takes into account the design features of the modular construction of a machine-tractor unit. (Results and discussion) The authors showed that for a modular power unit with a 6K6 wheel arrangement, it is necessary to consider a number of additional factors having an impact on the accuracy of the calculation: firstly, the tractor’s traction and coupling properties depend on the number of driving axles; secondly, the wheel slippage along individual axes is not the same and occurs due to a constructively conditioned kinematic discrepancy in their drive; thirdly, the three-axle transmission efficiency can be determined only as a total indicator of three transmission branches, that is, to drive the tractor front and rear wheels and, separately, to drive the wheels of the technological module. The authors compared the required engine power when using a tractor with ballast and that with a technological module.  (Conclusions) It was determined that in order to achieve the maximum traction force of adhesion on the hook when moving to the next higher traction class, it is necessary that the tractor, that the technological module is joint to, has the energy saturation of 2.00-2.41 kilowatts per kilonewton, which corresponds to traction and energy concept tractors whose engine power cannot be realized through traction. It was found that the power saturation of the tractor with the technological module will be equal to 1.59-1.65 kilowatts per kilonewton, which corresponds to the tractor of the traction concept and allows realizing the built-in engine power through traction.

Engine Power

A method for estimating the power characteristics of the car engine in various driving regimes is proposed. It is determined that the volume of the free power (engine power reserve) allows the driver to implement the turning parameters and the time of its completion, which are set by the steering parameters, position and the speed of the steering wheels rotation. The engine power reserve is necessary to provide the required maneuverability indicators. The engine power during maneuvering is spent on overcoming the resistance to movement and on providing the impact controlled by the maneuver. The first component of the engine power can be called connected, and the second one can be called the free one or a controlled component. The received analytical expressions allow carrying out at the design stage a rational choice of capacity of the engine by the condition of maintenance of demanded properties of maneuverability. The developed method for constructing the refined acceleration characteristics of the engine makes it possible to determine the dynamic capabilities of the car, taking into account its design features and operating conditions.

Engine Power

The main reason for using heavy tractors is the high energy saturation of modern agricultural machinery. For the full engine power realization, the tractor must have high traction performance. Ballasting, the drive wheels doubling, transport and technological modules increase traction. (Research purpose) To determine the best way to increase traction. (Materials and methods) The authors calculated the propulsors pressure of the Terrion 3180 tractor loaded with ballast weights and aggregated by the MES-300 transport and technological module on the soil using mathematical modeling. It was noted that the pressure on the soil is 38 percent less when using the transport and technological module, with the same traction. (Results and discussion) The authors analyzed the design of the MES-300. It was revealed that to improve the transport and technological module operation, it was necessary to reduce weight. It was found that when using the transport and technological module to increase the tractor traction, fuel consumption increased by an average of 3 percent. The authors showed that it was possible to reduce consumption by improving the transmission, which was based on the drive axle from the T-150K tractor. They found out that the effective drive scheme was an individual drive of the drive wheels, which allowed to combine the positive sides of the differential and hard drive. They performed mathematical modeling of a transport and technological module with various types of transmission (mechanical, hydrostatic, electric). It was stated that hydrostatic transmission was the most efficient type of transmission in terms of fuel economy. (Conclusions) The authors determined that the modernization of the MES-300 through the use of a transmission with an individual drive on each wheel had positive results: a change in power and torque supplied to each wheel; reduction in kinematic mismatch and power circulation; increase fuel efficiency.

Now days there is no a single mass-produced vehicle for agriculture which does not match requirements of the state standard for the maximum allowable impact of movers on the soil. This leads to significant losses and under-harvest of agricultural products. As a promising direction for increasing the efficiency of the transport infrastructure of agricultural production, it is proposed to develop an environmentally friendly transport and technological chassis for agricultural purposes.

Due to the spread of small-sized loaders with on-board swing system (SLOS), it has become necessary to determine the level of their technical development. To understand the set task, a review of small-sized loaders, their classifications, performance parameters and implements was made. Modern SLOS manufacturers were analysed; their design features; main operating parameters: engine power, load capacity, speed and vehicle weight. An analysis of recent papers describing SLOS performance was conducted. It should be noted that most of them consider specific workflow processes, design features that do not reflect the full range of such machines. To solve this problem, a statistical analysis of theSLOS nomenclature data was performed depending on the classification features and performance indicators. This article presents the assessment of the impact of SLOS performance parameters and classification features on their level of technical development. Based on statistical data, the regression equations of the dependences were obtained: engine power on load capacity; loader weight on load capacity; dependences of performane parameters were plotted. General trends in the technical development of small-sized loaders were established. The vast majority of manufacturers focus on the production of medium-capacity loaders, as they are in the greatest demand. The analysis of the graphs suggests that in the future production of small-sized loaders with the load capacity of up to 1.5 tons, engine power of 60-70 kW and weight of up to 5 tons will increase. We can also predict growing production of compact SLOS with the load capacity of up to 0.5 tons, engine power of 20-30 kW and weighing up to 2 tons, which are widely used in urban landscaping. With the help of the present paper we can predict development trends, establish weaknesses of modern SLOSs and avoid competition when designing new loaders.

Abstract A method for determining the effect of suspension dynamics on tire wear has been developed. Typical city cycle maneuvers are defined by instrumented vehicle testing and data in the form of forward velocities and steer angles are used as an input to an ADAMS computer model of the vehicle. A simulation of the maneuvers generates a tire's operating environment in the form of normal load, slip, and camber variations, which contain all the subtle effects of the vehicle's suspension, steering, and handling characteristics. A cyclic repetition of the tire's operating environment is constructed and used to control an MTS Flat-Trac machine. In this way, accelerated tire wear can be generated in the laboratory which is directly related to the design features of the vehicle's suspension and steering systems.
