摘要
为研究矿砂物理状态的变化情况,在模型货舱上加装8组传感器,包括含水率传感器、压力传感器和应变传感器。通过摇摆台试验,全程监测铁矿砂液化演变过程中的3种数据,并对数据进行分析对比,发现在矿砂表层出现液化前,水分子具有较大的向上运动速度,为进一步揭示矿砂水分子的运动规律,从3个维度去感知分析矿砂状态的变化,结合实船矿砂测试数据分析,验证实验室的试验结果,得到传感器更优的安装位置,为矿物液化监控系统的开发奠定基础。
In order to monitor the physical state changes of ore,8 sets of sensors are installed in the model cargo compartment,including moisture content sensor,pressure sensor,and strain sensor.Through shaking table tests,three kinds of data reflecting the process of iron ore liquefaction evolution are collected.By analyzing and comparing the data,it is found that water molecules have a higher upward velocity before liquefaction occurs on the surface of ore sand,which reveals the movement rule of water molecules in mineral sand.The change of ore state is examined in three dimensions.The analysis of real ship sand test data supports the results of the laboratory tests.The tests suggests appropriate installation positions of the sensors,which lays a foundation for the development of mineral liquefaction monitoring system.
