| description | In response to the low threshing efficiency of millet ear petals, this study investigated the tensile and impact mechanical properties of millet petals during the millet threshing process. Jingu 21, Zhangza 16, and Changza 466 were used as experimental subjects to study the effects of tensile angle and growth part on fracture strength, and to determine the influence of impulse and growth part on drop and breakage rates. The results indicated that both growth part and tensile angle have a highly significant impact on the tensile fracture strength of the millet petals. The tensile fracture strength decreases with the increase in the tensile angle, and increases with the growth part from top to bottom. The variety, growth part, and impulse significantly affect the impact drop and breakage rates of the millet petals, with the main factors affecting the drop rate being impulse, variety, and growth part, in that order. When the impulse is 2.296 N·s, the threshing effect for Jingu 21 is optimal, with a drop rate of 65.091% and a breakage rate of 13.487%. This research provides theoretical insights into the simulation of the millet ear threshing process and the optimization of the performance of millet threshing equipment. |
