In the heart of Ukraine, a groundbreaking development is poised to revolutionize the agricultural and energy sectors. Researchers at the Institute of Mechanics and Automation of Agro-Industrial Production of the National Academy of Agrarian Sciences of Ukraine have introduced the MEV-115 “Autotractor,” a mobile energy vehicle designed to enhance the efficiency and safety of machine and tractor units (MTUs). The research, led by V. Adamchuk, has been published in the journal “Machinery & Energetics” (translated from Ukrainian as “Machinery and Power Engineering”).
The MEV-115 “Autotractor” is not just another vehicle; it’s a technological marvel equipped with a centralized tyre pressure control system, a sophisticated hydraulic system, and a frame-based technological module (TM) mounting system. One of its standout features is the rear three-point hitch, which allows for the aggregation of TMs weighing up to 2 tonnes. This compact design ensures that the TM can be mounted onto the vehicle frame without the need for disassembling the hitch, a significant advancement in operational efficiency.
The research conducted by Adamchuk and his team focused on experimentally determining the effect of the TM’s mass on the axle loads of the MEV. Using strain gauge scales, they verified theoretical calculations on the distribution of axle loads in the MEV depending on the weight and centre of mass of the TM. The findings are critical for ensuring the stability and load distribution in MTUs, particularly those with MEVs based on high-mobility truck platforms.
“Our research has established critical TM parameters for safe operation,” said Adamchuk. “We’ve determined the distance from the TM’s centre of mass to the rear axle and the TM weight that ensure balanced axle loads, eliminating parasitic power circulation between the axles of the MEV-115 ‘Autotractor’.”
The results of the study have far-reaching implications for the energy sector. By optimizing the design and use of MEVs, the research paves the way for more efficient and safer agricultural practices. The findings can be applied to enhance MEV design, ensuring that these vehicles operate at peak efficiency while maintaining operational safety.
One of the key findings was the determination of the minimum front axle load necessary to maintain steerability during transport operations. This is at least 20% of the total MTU weight, a critical factor for ensuring the safety and efficiency of these vehicles in the field.
The research published in “Machinery & Energetics” not only validates the theoretical models but also demonstrates the effectiveness of the approach. The findings are set to shape future developments in the field, offering a blueprint for the design and optimization of MEVs in agricultural production.
As the world looks towards more sustainable and efficient agricultural practices, the MEV-115 “Autotractor” stands as a testament to the power of innovation and research. With its advanced features and proven effectiveness, it is poised to become a game-changer in the agricultural and energy sectors. The research led by Adamchuk is a significant step forward, offering valuable insights and practical applications that will drive the future of agricultural technology.
