摘要
研究带球冠体封头的卧式储油罐在变位条件下的罐容标定问题,采用微元法建立油罐储油量与油位高度及变位参数之间的计算模型。为了得到变位参数的有效估计,对进出油实测数据建立非线性的最小二乘回归模型,在数值求解中,采用截面积的微元方法,有效减少了复杂的体积积分计算,从而完成罐容表的修正标定。
This paper presents a novel mathematical paradigm for solving the volume table calibration of the inclined oil tank with spherical crowns. The general relationship of the oil volume, height of oil level and parameters of position change is rigorously derived on the differential element method of inte- gral. We develop the non-linear of least squared regression model to estimate the parameters of position change. In particular, the differential element method of the sectional area is proposed to effectively reduce the complex numerical computation of integral. Therefore, the volume table is readjusted by the estimation of parameters of position change.
