| 为实现大宗散货自动化装船，设计一种以平衡装载原则、货物堆积平整度和船舶安全性为基础，利用散货物料堆积特性建立理想锥体模型近似模拟物料平整堆积装船效果，建立散货装船物料堆点布置及对应装载量的自动规划策略，提出一种具有自我影响因子的改进型黄金分割法，快速构建理想平整堆积模型，优化自动规划算法效率，最后通过实验验证自动装船策略规划及算法．结果表明：改进的黄金分割法比传统黄金分割法能够更准确、快速地找到平整堆积模型参数的最优值，优化效果明显；实验测量和算法模型的堆点堆高最大平均相对误差在7%范围内，证明散货装船规划策略在实现散料平整堆积上具有良好的准确性、适用性． |

| In order to realize the automatic loading of bulk cargo, according to the stacking characteristics of bulk materials, an ideal cone model is designed based on the principle of balanced loading, the flatness of cargo stacking and the safety of the ship. The ideal cone model is used to simulate the effect of the smooth stacking loading of bulk cargo, and the automatic planning strategy of the material stacking point layout and the corresponding loading capacity is established. An improved golden section method with self influence factor is proposed to quickly build the ideal flat stacking model and optimize the efficiency of automatic planning algorithm. Finally, the automatic shipping strategy planning and algorithm are verified by experiments. The results show that: compared with the traditional golden section method, the improved golden section method can more accurately and quickly find the optimal value of the flat stacking model parameters, and the optimization effect is obvious; the maximum average relative error of the stacking point height measured by the experiment and the algorithm model is within 7%, which proves that the bulk cargo loading planning strategy has good accuracy and applicability in realizing the smooth stacking of bulk materials. |
