摘　　要：为了揭示组合式轴流脱分装置稻谷脱分过程中应力分布规律,以螺旋叶片板齿组合式轴流脱粒与分离装置为研究对象,采用应力原理建立应力模型,通过仿真技术获得了应力分布规律。试验表明:稻谷脱分过程中的应力在轴线方向上有上下波动的趋势,且变化是不均匀的;在变化的过程中出现了两个高峰值,分别是在脱离滚筒的前期和中期阶段;脱分过程结束是在稻谷喂入端沿着轴线方向2.35m左右的距离处。In order to reveal distribution regularities of grain stress in axial flow threshing and separating process , based on the principle of stress ,the stress mode of the assembled of plank-tooth and helical vanes is set up .The distribution regularities of force in the threshing and separating space was obtained .The result indicate that distribution regularities is irregular along axial direction , two peak value of circumferential distribution appear in portion and intermediate section of cylinder .threshing and separating process finish about 2 .3 kilometers from the mouth of feeding .
