摘要: 为减少工业大麻机械化收割过程中工业大麻茎秆破损和折断现象,采用ANSYS软件和SolidWorks软件建立工业大麻茎秆柔性体和输送机构模型,并将其导入Adams软件中建立工业大麻茎秆输送机构刚柔耦合模型,以最大碰撞接触力为指标,利用正交试验方法进行仿真试验,根据试验结果分析下水平输送链位置,上压簧位置,上水平输送链位置,输送速度的变化对茎秆受到输送机构最大碰撞接触力的影响显著性和影响规律,以及最优作业参数组合。结果表明:下水平输送链位置对最大碰撞接触力的影响极显著(P<0.01),显著性顺序从大到小为下水平输送链位置、上压簧位置、输送速度、上水平输送链位置、上水平输送链位置与下水平输送链位置交互和下水平输送链位置与上压簧位置交互。并且当上水平输送链位置695 mm,下水平输送链位置为270 mm,上压簧位置为380 mm,输送速度为0.9 m/s时,最大碰撞接触力最小,为123 N。

Abstract: In order to reduce the breakage and breakage of industrial hemp stalks during the mechanized harvesting of industrial hemp, ANSYS software and SolidWorks software were used to establish the flexible body and conveying mechanism model of industrial hemp stalks, and then imported into Adams software to establish the industrial hemp stalktransporting mechanism Rigidflexible coupling model, using the maximum collision contact force as an index, using the orthogonal test method to conduct simulation tests, according to the test results to analyze the position of the lower horizontal conveying chain, the position of the upper compression spring, the position of the upper horizontal conveying chain, and the change of conveying speed on the stalk The significance and law of the influence of the maximum collision contact force of the conveying mechanism, as well as the optimal combination of operating parameters. The results show that the position of the lower horizontal conveyor chain has a very significant effect on the maximum collision contact force (P<0.01), and the order of significance from large to small is the position of the lower horizontal conveyor chain, the position of the upper compression spring, the conveying speed, and the position of the upper horizontal conveyor chain, The position of the upper horizontal conveyor chain interacts with the position of the lower horizontal conveyor chain, and the position of the lower horizontal conveyor chain interacts with the position of the upper compression spring. And when the position of the upper horizontal conveyor chain is 695 mm, the position of the lower horizontal conveyor chain is 270 mm, the position of the upper compression spring is 380 mm, and the conveying speed is 0.9 m/s, the maximum collision contact force is the smallest, which is 123 N.
