为给苗木嫁接机器人切削系统的研制提供设计依据和有关设计参数,自制苗木压伤试验装置和苗木切削试验装置,选取南方常用、材质较硬的砧木毛桃苗作为试验对象,对毛桃树苗进行抗压伤和切削力学特性试验.试验结果得出毛桃树苗抗压伤极限载荷、毛桃苗切削最大阻力和刀片的最小极限切削线速度;以及影响毛桃苗切削的因素关系,苗木直径、转速、滑切角依次影响切削阻力大小,苗木直径与切削阻力呈平方关系;转速与切削阻力呈线性关系;滑切角与切削阻力也呈线性关系.综合试验得出:毛桃苗抗压伤极限载荷为20.35 N;切削最大阻力为7.34 N,最小极限切削线速度为0.312 m/s;苗木直径较大地影响切削阻力,转速较大地...

In order to study the cutting system of seedling grafting robot and obtain its design data, the seedling test beds have been developed and re-compression and cutting experiments on peach grafting-seedling for sticking were carried out, which is being more often used in South China and its material quality is harder. On the basis of experiments, the experimental results show the limited load of anti-compression, the highest cutting resistance and the minimum cutting line-speed, and show that the diameter of seedling, rotation speed and angle of slide cutting respectively influence the cutting r...
