1、高速插秧机稀植分插机构仿真分析与试验尹建军江苏大学现代农业装备与技术教育部重点实验室摘要:针对超级稻大株距稀植要求,提出一种棊于双转臂式差动椭闘齿轮系稀植分插机构,适合栽插株距从20(f280mni、秧甫高度小于35(b腦的毯状秧苗。使用SolidWorks对提出的稀植分插机构进行三维建模,检验其装配关系和结构设计合理性。基于ADAMS软件对该分插机构进行动力学仿真分析,得出该分插机构的秧针尖点轨迹、速度、加速度,以及齿轮箱各级椭圆齿轮啮合力和中心轮轴力矩曲线。基于图像处理对提出的稀植分插机构样机进行运动轨迹和姿态测定试验,结果表
2、明:所得的测试结果与Adams仿真所得结果一致。根据现有设备及插秧试验台架对上述空载试验分插机构进行插秧试验,得出取秧率为100%,插秧直立度接近90°o关键词:水稻;分插机构;椭岡齿轮;ADAMS;作者简介:饶师任(1989-),男,江西抚州人,硕士研宂生,(E-mail)raoshiren@163.com。作者简介:陈树人(1965-),男,湖南攸县人,教授,(E-mail)srchen@ujs.edu.cn。收稿日期:2016-12-03基金:镇江市重点研发计划项目(NY2015009)SimulationandExperi
