Abstract:
In order to study the damage mechanism of soybean seed threshing process, in this paper, the transient structural analysis of the cycle of single particle stripping of the thawed pegs was carried out. Then, the three kinds of impact parameters were analyzed by the mixed level total factor analysis. Finally, the theoretical model of the impact process was established, analysis of the results and theoretical model analysis.It was found that the maximum stress appeared in the seeds near the impact site, and there was residual stress in the soybean seed after the impact process. The tooth shape and impact sectional area had a significant effect on the maximum stress in the process. Compared with the straight tooth, the maximum stress is reduced in the case of the arch tooth, and the maximum stress decreases with the increase of the impact sectional area.
