中文摘要：

金属油罐具有热胀冷缩的特性,在标准温度下测得的容积在其他温度下会发生变化,为得到该温度下的容积,需要对金属油罐的内壁变形规律进行研究。基于ansys建立了半地下立式金属油罐的有限元模型,并作了温差载荷下半地下立式金属油罐的静力学分析,为进一步的容积变化计算提供了条件。

英文摘要：

Metal tanks have the characteristics of thermal expansion. Volume measured at standard temperature changes at other temperatures. In order to obtain the volume of the temperature,the deformation of the inner wall of the metal tank should be study. This paper built the finite element model of semi-underground vertical metal tanks base on ansys software,and made static analysis of semi-underground vertical metal tanks at temperature difference load. All of these works provide the conditions for change in the volume calculation.
