摘　　要：文章为有效处理储油罐变位标识以及罐容表标定相关问题,经由对储油罐横向偏转以及纵向倾斜带给罐容表影响表现的方式,构建获得罐体变位的情况下,实际储油量以及显示油位高度两者的分析模型。其中,针对变位标识问题,能够经由定积分的方式来实现横截面顺着罐体底面来完成积分作用的方式构建并且检验储油罐v以及油位高度h相关的初始模型。同时,参照绝对误差以及油位高度情况完成拟合分析,获得补偿函数f(x),将其与初始模型完成组合作用的情况下,能够获得修正完成罐容表后对应着的标定模型;针对罐容表标记问题,考虑到储油量的体积就是球罐以及圆柱体两者油量体积的综合,前者经由球冠蒙塔卡罗法(样本量N=100000)完成求解,如此就能够获得油位以及变位相关参数关系。In order to effectively deal with the problems related to the tank displacement identification and tank capacity meter calibration,this paper constructs the analysis model of the actual oil storage capacity and the displayed oil level height under the condition of tank displacement by analyzing the influence of the lateral deflection and longitudinal tilt of the tank on the tank capacity meter.Among them,for the problem of displacement identification,we can achieve the integration of cross section along the bottom of the tank through definite integration,build and test the initial model of oil tank V and oil level height H.At the same time,according to the absolute error and oil level height,the fitting analysis is completed,and the compensation function f(x)is obtained;Considering that the volume of oil storage is the combination of the volume of oil storage of spherical tank and cylinder,the former is solved by ball crown montakaro method(sample size n=100000),so that the relationship of oil level and displacement related parameters can be obtained.
