Mathematical Modeling and Evaluation of the Transport and Technological Module Drive Efficiency

Abstract

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.
