摘要
许多油气罐在使用一段时间后,由于地基变形等原因,使罐体发生变位从而导致罐容表发生变化。本文采用微元法,建立了油罐储油量与液面高度及变位参数之间的计算模型。用Mathematica软件计算出了罐体纵向倾斜角为0°和4.1°时,油位高度间隔为5cm的标定罐容表。
Atter oil-storage tanks have been used for a period of time, considering the deformation of the ground and other reason, the location of tanks will be changed, which will result in changes of the tank-capacity charts. 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 integral. We gave the tank calibration value of capacity charts of longitudinal displacement angle and .
