MATHEMATICAL MODEL OF THE INVERSE PROBLEM OF DEFORMATION OF OIL TANK BOTTOM

摘要

Nowadays, to predict the deformation of the bottom of oil tank has been an urgent problem of oil storage and processing enterprises in transportation engineering. Using body-fitted coordinate system, the inverse problem mathematical model of the deformation of the bottom of oil tank is established, and the two-dimensional oil reserve integral expressions are derived. Between oil reserves, vertical angle, heeling angle and the oil level height, the relative function is derived. Our prediction value of oil reserves is compared with the actual measured one, and the accuracy is higher than 95%.
