摘　　要：钵体苗吹出是气力有序抛秧一个主要的环节。为此,运用ANSYS/LS-DYNA软件对钵体苗吹出过程进行了有限元模拟分析,通过对其分析计算,得出了位移、应力和应变等结果云图,以及相应的应力时间关系曲线,为气力有序抛栽提供理论依据。The blowing rice seedling is a important section of the ordered pneumatic throwing,the procedure of the blowing rice seedling is simulated and analyzed by using ANSYS/LS-DYNA in this paper,the result of displace,stress,strain were obtained by cloud chart,and the corresponding stress-time curve was also got.All these provided some theoretical reference for the ordered pneumatic throwing.

关 键 词：钵体苗 有序抛栽 有限元 位移
