耙吸挖泥船耙头密度估计器研究与分析

Research and analysis on drag head density estimator of trailing suction hopper dredger

针对新型耙头的挖掘模式,利用黑箱模拟法与在线滚动优化预测理论,设计了一种耙头吸入密度估计器,采用现场实测数据进行了仿真实验。结果表明,该密度估计器可以较为准确地预测耙头底部的吸入密度,在疏浚作业中实时提供连续的混合物吸入密度信息,及时指导操作人员针对不同工况调整疏浚参数,满足高效疏浚的需求。

Based on the new type drag head of digging model, we used the black-box simulation and online rolling forecast to design a drag head density estimator, and carried the simulation experiment with field data. It proved that the estimator can accurately predicting the inhalation density, can provide continuous real-time to the operators when the density of the mixture inhaled dredging, can let the operator according to different working conditions to adjust each subsystem, and can meet the efficient dredging requirements.
