摘要
针对小椭圆罐体在实际应用中常见的三种纵向倾斜情况,分别建立了油量与油位高度之间的二重积分模型。用MATLAB得到相应的数值积分方程并进行数值计算。由模拟值与实测值的误差与液位高度的抛物线关系,进行二次回归。用回归函数修正了模型,得到精确度可达到99.6%的储油量计算模型。
According to the small oval oil tank tilted in three common conditions practically,the double integral model of oil reserves with oil level height respectively is established,The corresponding numerical integral equation and simulated values by MATLAB are got.Based on the parabolic relationship of the issue of the simulated values and the measured values with the liquid level,the quadratic regression could bedone.The model with the regressive function to obtain the oil reserves calculation model with accuracy of 99.6% is modified.
