| 目的 针对强异构货物垛型稳定性判定问题，提出一种稳定性计算方法。方法 首先运用静力学和动力学分析，建立物理模型，量化5个稳定性参数，定义定量评估垛型稳定性的指标——垂直稳定度和水平稳定度，然后分别采用中心骨架算法、分支定界算法、Extreme Point算法建立仿真垛型，对比货物的空间布局位置及布局效果，通过计算公式得到垂直稳定度和水平稳定度数值，对垛型的稳定性进行机理分析，最后，采用小规模纸箱实验，进一步验证公式的合理性。结果 提出的稳定度计算公式能有效用于强异构性垛型的稳定性评估与分析。结论 该方法对提高码垛算法的工程应用性，增强配平均衡性，防止货物在地面运输过程中倒垛，具有一定的参考价值。 |
| 英文摘要: |
| The work aims to propose a stability calculation method regarding the problem of determining the stability of strong heterogeneous stack type. Firstly, statics and dynamics analysis was carried out to establish the physical model, five stability parameters were quantified, and the indicators (vertical stability and horizontal stability) for quantitatively evaluating the stability of stack type were defined. Then, the central skeleton algorithm, the branch and bound algorithm, Extreme Point algorithm were respectively used to establish the simulation stack type, compare the spatial layout position and layout effect of goods, obtain the vertical stability and horizontal stability by calculation formula, and analyze the mechanism of the stability of the stack type. Finally, the small-scale carton experiment was carried out to further verify the rationality of the formula. The stability calculation formula proposed herein could be effectively used for the stability evaluation and analysis of strong heterogeneous stack type. The method has certain reference value for improving the engineering applicability of the palletizing algorithm, enhancing the safety of air baggage trimming, and preventing the cargo from falling down in the ground transportation process. |
