摘要
针对储油罐在使用一定时间后会发生变位即纵向倾斜和横向偏转导致罐容表度量不准确的问题,利用修正的积分方法分别建立椭圆油罐变位后储油量与油位高度模型和两头为球冠体储油罐变位后储油量与油位高度模型及变位参数确定模型,针对上述模型通过Matlab软件求解,得到了重新标定的椭圆储油罐和两头为球冠体储油罐的油量表,确定了储油罐的纵向倾斜为2.1?,横向偏转范围为4.1?到5.1?.
In paper, the models are set up by modified integral method to recognize the displacement of oil tank and rescale the fuel meter after the tank is tilted. Based on the investigative data, the fuel meters are rescaled and the optimal numerical values of two parameters are proposed. The longitudinal inclination is 2.1° and the lateral inclination is 4.1°-5.1°
