Abstract

Background. Agricultural production is facing a shortage of tractors due to insufficient available machinery. To address this issue, a technological module was developed to increase the versatility of Class 1.4 tractors by upgrading them to a higher traction class. To assess the operational safety of a tractor equipped with a technological module, the maximum static climbing angle was calculated.

Purpose. Theoretical calculations were conducted to determine the maximum static climbing angle of a modular power and technological vehicle.

Materials and methods. The stability of the MTZ-82 tractor equipped with a technological module, including the coordinates of the overall center of gravity and the maximum static climbing (slope) angle, was analyzed using computational models.

Results. The horizontal and vertical coordinates of the center of gravity of the tractor and technological module were found to be 0.38 m and 0.885 m respectively. The maximum static climbing angle of the MTZ-82 tractor with technological module was found to be 71.7°.

Conclusion. Theoretical calculations of the maximum static angle of ascent have shown that the modular energy technology device is capable of performing the full range of technological operations without compromising operational safety.
