摘　　要：2ZQP-1型气力有序抛秧机是一种新型水稻钵苗栽植机械。为了揭示其作业机理,在显式非线性动力学理论的基础上,利用ANSYS/LS-DYNA软件建立了抛秧机作业时钵苗从育秧塑盘穴孔吹出及与导苗管壁发生碰撞的有限元模型,通过模拟计算获得了钵苗吹出和碰撞的运动规律,为优化水稻钵苗栽植机零部件参数提供了依据。as 2ZQP-1 ordered pneumatic throwing transplantation machine is a new type machine of paddy pot seedling planting. In order to opening out working mechanism of the machine, on the basis of explicit nonlinear dynamic theory, as the machine working, FEA models of pot seedling being blew out from the hole of plastic pan and colliding with the wall of guide seedling tube were built by ANSYS/LS-DYNA software. Through simulating calculation, moving rule of pot seedling was obtained, and offered basis for parameter optimizing of related parts.
