摘要
储油罐罐底变位预报是目前从事油品储存加工企业急需解决的一个问题。运用贴体坐标系,建立了储油罐罐底变位逆问题数学模型,推导出相应的变位计算公式,得到储油罐中的油量与纵向偏转角度、横向偏转角度及油位高度读数之间的关系,计算出变位角,该变位角对应的储油量预报值与实际测量值吻合度高达95%,其罐容表重新标定方法具有实际应用价值。
Nowadays,it is an urgent problem to predict the deformation of the bottom of oil tank in oil storage and processing enterprises.Using body-fitted coordinate system,the mathematical model for the inverse problem of the deformation of the bottom of oil tank was established,and computing formula for deformation was derived.After obtaining the relationship among oil reserves and vertical deflection angle,horizontal deflection angle and the oil level height,the deflection angle was calculated.The prediction value of oil reserves agrees with the actual measured value to the degree of 95%.The re-calibration method for tank volume meter is practical.
