| 摘 要： | 探讨储油罐的变位识别与罐容表标定问题。通过设置合适的坐标系,使用截面分析和近似简化、坐标变换等技巧,推导出椭圆型小储油罐和实际储油罐在发生变位时,储油量与油高之间的函数关系;对照理论计算与实验数据,发现非线性误差,运用函数拟合,对模型做出修正,并利用实验数据验证了修正的有效性;针对实际储油罐的测量数据,通过最小二乘法确定油罐的变位参数,并对数据结果进行了具体分析。

| Abstract: | This paper discusses the identification of oil tank deflection and calibration of tank capacity table.By setting appropriate coordinate system,the author points out the functional relationship between oil storage and oil level when small oval oil tank and actual oil tank deflect with each other,using skills such as cross-section analysis,appropriate simplification and alteration of coordinates.Comparing the theoretical calculation with experimental data,we find nonlinear discrepancy,therefore,we make amendment to the model and verified the validity of the amendment using function fitting.As for the measurement data of actual oil tank,the author analyses the data thoroughly through the deflection parameters of the oil tank determined by least-square method. |
