摘　　要：吊杯是吊杯式移栽机的核心部件,其运动过程将直接影响到秧苗的移栽质量。因此,对于吊杯的运动分析显得尤为重要。目前,许多学者已研究了吊杯运动的轨迹对移栽质量的影响,但吊杯的杯嘴运动对于栽植效果的影响并未进行相关研究。为此,基于Pro/E完成了吊杯式栽苗器各零部件的三维实体建模,并进行吊杯式移栽器的虚拟装配和运动仿真分析。仿真结果:测得了杯嘴运动过程的位移-时间特性曲线,分析得到了栽苗器杯嘴的最大开口宽度和杯嘴的开口运动时间,为优化吊杯式栽苗器的结构提供了基础数据和理论依据。Dibble is one of the core components of transplanter, and the motion process of dibble will directly affect the quality of seedling transplanting. Therefore, it＇s very important to analysis the movement process of dibble. At present, Dibble＇s trochoid has been analyzed and verification through some articles, but the planting effects about motion process of dibble openning mouth are not researched. This paper had finished 3D modeling, virtual assembly and movement sim- ulation analysis of dibble basing on Pro/E. The results of simulation had measured the motion displacement-time charac-teristic about mouth of dibble, and then the result will provide us essential data and theory basis for nacelle optimal struc-ture designing.
