中文摘要:
      目的 解决袋装成品粮集装箱内码垛时落袋不规则、落袋点模糊影响码垛位置精度的问题。方法 本文采用ANSYS/LS-DYNA对袋装成品粮落袋过程进行仿真分析,并搭建袋装成品粮落袋试验平台进行试验,使用高速摄像机观察袋装成品粮落袋过程,分析袋装成品粮输送速度、落袋高度在落袋过程中的应力分布及落袋机理,确定最大等效应力出现的区域以及最佳落袋参数组合,验证仿真研究的准确性。结果 仿真结果表明,袋装成品粮在离地600 mm跌落后水平位移相对较少,且输送速度越小成品粮跌落后的水平位移越小。成品粮跌落冲击地面时,所受冲击应力集中在下层中部。结论 堆垛码垛系统水平运输,输送速度为0.7~1.0 m/s、输送高度为200 mm时袋装成品粮能够被水平推送出输送带末端,输送速度为0.3 m/s、输送高度为600 mm时袋装成品粮翻转落袋到地面姿态最佳,且在水平方向上的平均位移最小,满足袋装成品粮集装箱自动装卸装备的末端落袋工作需求。有限元模型与实际落袋位姿情况基本符合,对袋装成品粮集装箱自动装卸装备的末端落袋位姿分析具有一定的参考。
英文摘要:
      The work aims to solve the problem of irregular bag drop and fuzzy bag drop point affecting the accuracy of palletising position during palletising of bagged finished grain containers. ANSYS/LS-DYNA was adopted to simulate and analyse the bagging process of bagged grains and set up a bagged grain bagging test platform for testing. A high-speed camera was employed to observe the bagging process of bagged grains, analyse the distribution of stress and bagging mechanism of bagged grains, conveying speed and bagging height in the process of bagging, and determine the region where the maximum equivalent force occurred, as well as the optimal combination of bagging parameters. Then, the accuracy of the simulation was verified. According to the simulation results, the horizontal displacement of the bagged grains was relatively less when it fell 600 mm from the ground, and the smaller the conveying speed was, the smaller the horizontal displacement of the grains after falling was. When the finished grains fell to the ground, the impact stress was concentrated in the middle of the lower layer. When the stacking and palletising system adopts horizontal transport, the bagged grains can be pushed out of the end of the conveyor belt horizontally when the conveying speed is 0.7~1.0 m/s and the conveying height is 200 mm, and the bagged grains can be turned over and dropped to the ground when the conveying speed is 0.3 m/s and the conveying height is 600 mm, which is the best dropping position, and the average displacement is the smallest in the horizontal direction, meeting the requirements of the end-drop bag work for the automatic loading and unloading equipment of bagged grain container. The finite element model is basically consistent with the actual bag drop position, which is a reference for the analysis of the end bag drop position of automatic loading and unloading equipment for the bagged grain container.
