摘　　要：采用拟蒙特卡罗模拟算法对倾斜储油罐进行储油量测定、变位识别及倾斜角度计算,并针对不同情况设计4种算法。在储油罐空间内产生均匀分布随机点,并通过统计油平面位置以下随机点个数,估算当前油面高度的储油量,利用空间坐标变化确定变位后储油罐的空间位置,估算当前位置下油面所反映的储油量。以某油罐加油实测数据为例,根据油面高度、理论储油量、测量储油量、出油量判断罐体是否变位,并利用最小二乘法,采用网格遍历搜索计算得到倾斜角度,结果表明计算模型具有一定的可行性和可靠性。Quasi-Monte Carlo algorithms are used to carry out oil capacity determination, displacements recognition and tilt angle calculation of tilt oil tank, and four algorithms are designed for different situations. Uniformly distributed random points are produced in the space of oil tank. The number of random points below the oil level is calculated to estimate oil capacity at the current oil level height. Oil tank spatial location after displacements is determined using changes in the spatial coordinates, thus estimating the oil capacity reflected by the oil level at current position. Taking measured oil filling data in some oil tank as an example, it determines whether the tank body is displaced according to oil level height, theoretical oil capacity, measured oil capacity and oil pump capacity and obtains the tilt angle using the least square method and grid traversing search algorithm. The results show that the calculation model has certain feasibility and reliability. （2 Tables, 3 Figures, 4 References）
