摘　　要：供种装置是蔬菜播种装置中的重要部分,利用ANSYS/FOTRAN有限元软件对管道气吹供种装置内部流场进行了仿真分析,实现了管道气吹供种装置的优化设计。结果表明,管道入口气流速度在一定范围内变化时,同一方案管道内部气流场分布情况变化不大。比较各方案管道内的气流场分布,确定了管道气吹供种装置的最佳结构形式。Seed supply device is an important part of the vegetable seeding equipment. This research simulated the internal flow field of the pipe air - blown seed supply device by using ANSYS/FOTRAN finite element software, and realized the optimal design for the seed supply device. The results show that when the airflow velocity in the pipe entrance changed in a certain range, the internal flow field distribution of the pipe in the same program changed little. By comparing the internal flow field distribution of the pipe in different programs, the best structure of the pipe air - blown seed supply device was established.
