An important task in agricultural engineering and repair production is to improve the reliability of the working elements of agricultural machinery. This study presents the results of research aimed at enhancing the strength and wear resistance of tillage machine components.
One of the key aspects of the research is determining the stresses affecting the strength characteristics and increased durability of the working elements. This approach allows for more accurate predictions of their longevity and optimization of the design to extend their service life.
The study of new plowshares with a thickness of 12.5 mm made of 65G steel, as well as restored plowshares with welded strips of 45 steel, surfacing with Sormite, and vibratory strengthening for durability, was conducted in farms of the Poltava region at a plowing speed of 1.5…2.2 m/s. The new plowshares exhibited minor deformations, whereas the restored ones showed no deformations. Under standard operating conditions, the force at the plowshare tip ranged from 1500 to 2000 N. The average operational stresses in the critical section of the plowshare ranged from 250 to 320 MPa, which is significantly lower than the yield strength and endurance limit of 65G steel. Similar studies were conducted for cultivator sweep shares and opener discs. Empirical dependencies were derived during the calculations to determine the optimal thickness of tillage machine components for improved design and increased longevity.
Additionally, an analysis of wear intensity dependencies was carried out, allowing for a more detailed assessment of the impact of various factors on material strength. The results of comparisons with new working elements revealed that the restored components exhibited a 1.84…1.88 times lower wear rate, confirming the effectiveness of vibratory strengthening. Based on the research findings, recommendations were developed to improve the strength of materials and processing methods for working elements, enhancing their lifespan and operational efficiency.
