• 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 . to prevent the insufficiency or excess of sand water content , the amount of the first addition is set as 80 % of the total water addition amount . after the first water addition , we adopt ar model to predict the stable value of sand compactibility to shorten the time mixing the sand . each time we add water , the correction coefficient is introduced to adapt to the change in the composition of sand . the experiment shows that the mathematics model not only makes the water content in sand reach the best range within shorter time , but also directs how the sand composition should be adjusted , which can better conform to the actual situation
  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.为防止型砂水分不足或过量，将第一次加水量设定为总加水量的80 .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.每次加水后，引入修正系数，以适应型砂组成的变化.实验表明，该数学模型不仅使型砂水分含量在较短时间内达到最佳范围，同时可指示对型砂组成进行调整，能较好地符合实际情况
