摘要:为了提高任意油箱油量监测的精度，本文首先利用BIM技术建立目标油箱的三维模型，之后随机选取不同高度值剖切模型模拟油料液位变化的过程; 借助BIM算量功能，求出油箱总体积和每次剖切后的剩余模型体积; 最后采用最小二乘法对剖切高度比和油箱体积比进行多项式拟合，求出目标油箱油料消耗曲线。因BIM技术具有适应性强的特点，可以建立任意形状油箱模型并能快速计算其体积。并通过对比四种异形油箱的月实际加油量和系统加油量，证明了本方法的可行性，且达到了96.39%的准确率。相比较其他计算方法，该方法操作简单、成本低、精度高，在工程机械油量监测领域具有极为广泛的应用前景。
Abstract: In order to improve the monitoring accuracy of oil volume for arbitrary oil tank, the three-dimensional model of the target oil tank was established at first, using BIM technology in this paper, and then the model will be cut several times with different height that selected at random to simulate the changing process of oil level. After that, the total volume of the model and the residual volume of the model after cutting every time was calculated using BIM calculation function.Finally, under the application of least square fitting polynomial method, the oil consumption curve was obtained according to the data of cutting height percentage and volume percentage. Due to the better adaptability of BIM technology, the model of oil tank with any shape can be created and calculate its volume quickly. It is proved that the method with 96.39%accuracy is practicable by comparing the manual refueling volume with the system refueling volume within one month from four special-shaped oil tanks. Compared to other calculation techniques, this method is simple in operation, low cost and high accuracy, thus it has extremely wide application prospect in the field of oil volume monitoring on engineering machinery.
