| Popis: | The article presents the results of comparative studies of the stress-strain behavior of duck-foot tines made of steel and isotropic fiberglass. The studies were carried out on full-size 3D models of the SKP 01.08.080 (1) part being used on SZS-2.1 type seeders of various manufacturers widely spread in our soil and climatic zone. For the research, we used specialized software: CAD Autodesk Inventor and SolidWorks CAD/CAM system. Models were fastened and loaded using a distributed force of 650 N applied to the toe and wings of a duck-foot tine corresponding to the draught resistance of the part under conditions of its real operation at a speed of movement of up to 2.23 m/s. It has been shown that the deformations occurring in a duck-foot tine made of fiberglass 5...6 mm thick have a magnitude of 1.5...2 times less than those in a steel tine, the strength reserve factor of the steel and composite parts is the same and equals 15, however, its distribution over the part surface is uneven, so the predicted life cycle of the fiberglass part will be 2 times longer than that of the steel part. |
