摘要：Torevealstressdistributionrulesof grainseparating processin assembled axial flowthreshing andseparatingdevice, regarding assembled axial flowthreshing andseparatingdevice as object,High speed imaging technology is adopted in the shooting technique,stress model was set based on the stress principle, and stressdistributionrules was obtained by simulation technology.Grain, broken ear movement and the movement as a whole and free movement of the grain threshing process is through the analysis of the EXCEL drawing,The test resultsshowthat distributionrulesis irregularin grain separating process, is that, stressfluctuates ataxial direction,and two peak valuesappear at earlyandmiddle threshingstage respectively; threshing and separating processfinishesabout 2.35meters from the feedingmouthataxial direction. Off the spike in threshing and separating space motion unstable trajectory is a parabola, the speed decreased with the passage of time. No outside interference in the most free grain for approximate straight movement, in the medium of motion state, and axis direction and a certain angle.Therefore, grain rotorsdistribute ataxial directionand rest results are consistent with theory analysis.
