this paper analyzes the factors affecting the controlling precision of sand compactibility system and sets up the dynamic model of regression coefficient between sand compactibility and water content.
该系统能够用于在线检测型砂的紧实率、湿压强度和砂温等性能 ,并且能够根据检测结果通过控制补加水量将型砂紧实率控制在设定的工艺范围之内。
this paper analyzes the factors affecting the controlling precision of sand compactibility system and sets up the dynamic model of regression coefficient between sand compactibility and water content.
分析了影响型砂紧实率控制精度的因素 ,建立了型砂紧实率 -水分回归系数的动态模型 。
after the first water addition, we adopt ar model to predict the stable value of sand compactibility to shorten the time mixing the sand.
第一次加水后,对型砂紧实率稳定值采用ar模型进行预测,以缩短型砂混制时间。
