摘　　要：设计了一种以电磁铁为执行器的红枣自动分选机卸料装置,建立了基于ADAMS的卸料装置虚拟样机模型;通过虚拟单因素试验确定了卸料托杆的长度,并通过不同质量红枣的虚拟对比卸料试验,验证了模型的有效性,得到了果质量8g和果质量35g红枣的下落轨迹。虚拟试验结果表明,该模型在卸料托杆行程放大倍数为4时卸料效果最优,此时果质量35 g红枣的最大上升高度为100 mm,初始位置同水平侧向位移为60 mm;该模型能够将8～35g的红枣顺利卸料。A distributing apparatus and the model of virtual prototype were established by using the dynamic simulation software-ADAMS. The length of off-loading cam in this virtual prototype was determined through virtual single-factor tests,which proved the reliability of the model. The falling trace spline of jujube weighing tained. The results showed that the model can achieve the best effect when the magnificatio 4, with the culmination being 100mm and the horizon distance being 60mm respectively. could be distributed successfully. between 8g to 35g were oh- n times of off-loading Jujube weighing 8g cam is to 35g
