摘　　要：为了达到液态施肥机高速作业的目标,试验设计了一种运动平稳的椭圆齿轮行星系作为液态施肥机的扎穴机构。为满足喷肥针垂直入土、出土时扎穴深度120~150 mm的工作要求,设计参数为：椭圆齿轮长半轴29.364 mm、齿数23、短半轴与长半轴比0.958,正圆齿轮半径25 mm。应用三维造型设计软件Pro/E,绘制机构各零部件模型并装配,通过改变保存文件的类型实现Pro/E与ADAMS数据交换。在ADAMS中建立机构虚拟样机和运动学仿真,得到扎穴机构针尖的运动轨迹并进行分析。结果表明,应用虚拟样机技术可以实现扎穴机构的快速设计、准确分析,提高了设计速度,减少了设计成本。In order to obtain high working speed liquid fertilizer applicator,one kind of elliptic gear planetary galaxy,which had the steady movement,was designed as pricking hole mechanism of liquid fertilizer applicator.In order to meet the work requirements-pricking into and out of the soil vertically,the pricking depth was 120-150 mm,the appropriate parameters of mechanism were obtained： the semi-major axis of elliptic gear was 29.364 mm,the teeth quantity was 23,the ratio of semi-minor axes and semi-major axis was 0.958,the radius of circular gear was 25 mm.Based on three dimensional modeling design software Pro/E,components were drew and assembled to a whole.Through the changing preserved type of document,data exchange between Pro/E and ADAMS were realized.Virtual prototype model of mechanism was constructed,and kinematics simulation was carried on by using ADAMS,and then motion trajectory of the pricking hole mechanism was obtained.And the theoretical analysis was carried out to the simulation results.The results showed that virtual prototyping technology could realize rapid-design and exact-analysis in the pricking hole mechanism for liquid fertilizer applicator,which made the design speed increased but design cost reduced.
