Impact of Ship Bulbous Bow-Inspired Geometries on Draught Force in Soil Ripper Tools 1Kaunas University of Technology, Lithuania; 2Vytautas Magnus University, Lithuania This study proposes leveraging design principles from the marine industry, specifically the bulbous bows of ships, to address challenges in soil ripper design for agricultural machinery. New shape elements based on delta, oval, and nabla types of bulbous bows were developed. Thirteen newly designed elements, along with the original shape, were evaluated virtually using the Discrete Element Method (DEM), followed by draught force testing of 3D-printed samples in a sand bin. Draught force and energy results demonstrated good agreement between simulation and experimental tests, within standard error range. The slightly higher force values observed in simulations may be attributed to the influence of 3D printing layer height and particle-particle as well as particle-geometry interactions. The nabla-type sample N2 achieved the highest reduction in draught force (7.1%), while the nabla-type sample N3 showed the largest increase (4.1%) compared to the original design. Analysis of the samples' projected areas indicated that a smaller area generally reduces sand resistance, with the exception of the oval-type sample O3, which, despite a 32% reduction in projected area, did not show a corresponding reduction in draught force. For comprehensive evaluation, future research should include soil disturbance and wear analysis of the designed elements 12:00pm - 12:20pm
