摘　　要：为了降低研制成本,缩短研制周期,采用Solidworks设计水稻芽种直播机的虚拟样机。同时,对其排种器进行仿真分析,验证运动的可行性和合理性,得出推种杆推种端的运动参数,为下一步对芽种的充种和投种过程的仿真分析取得初始参数。对主梁的有限元静强度分析表明,采用两根Φ32×2.5的无缝钢管做主梁强度足够,危险部位在主梁前端下部处。分析结果可为物理样机制造提供参考。To reduce cost of manufacture, shorten of research, time, the direct seeder based on Solidworks software was designed. By simulation analysis the metering device, it＇ s workable and rational was test , and kinematic diagram of the seed roller in simulating was accepted . the main beam enunciated quiet strength of the main beam is enough by FEA test. The dangerous part is in the head and infrastructure of the main beam.
