Oil inventory

After liquid in oil tank was approximately treated on basis of Housner's theory, the finite element method is used to derive the mass matrix and stiffness matrix of the revolutionary shell.

利用豪斯纳理论对贮油罐罐内的液体作了近似处理 ,按有限元法考虑了回转壳的刚度阵及质量阵与贮油罐中液体的刚度阵及质量阵的组合 ,在此基础上重点分析了贮油罐的地震局部动力效应 ,即单元上连续质量惯性力的影响 ,对地震波激励下贮油罐的动力响应作了有限元分析 ,获得了一些有意义的计算结果 ,对贮油罐的设计有一定的参考价

Calulating formula of the reserve of horizontal cylindrical oil storage tank declined fiting at different liquid level is got used of integral method and how to use the formula is also explained in this paper.

用积分的方法导出了卧式倾斜安装圆柱体油罐不同液面高度时贮油量的计算公式，并举例说明其使用方法，为工矿企业对此种贮油装置进行油品盘点、成本考核及节油指标考核提供了可靠依据。
