应用有限元分析软件 ANSYS 对埋地输油管道的弯管(弯头)处的应力进行了数值计算与分析,得到了埋地输油管道在不同输油温度下弯管处所受应力的分布规律以及夹角变化、曲率半径变化对于弯头所受应力的影响规律.
應用有限元分析軟件 ANSYS 對埋地輸油管道的彎管(彎頭)處的應力進行瞭數值計算與分析,得到瞭埋地輸油管道在不同輸油溫度下彎管處所受應力的分佈規律以及夾角變化、麯率半徑變化對于彎頭所受應力的影響規律.

The numerical calculation and analysis of stress at the elbow of buried pipelines were carried out by using finite element analysis software ANSYS. The distribution law of stress at the elbow of buried pipelines under different operating temperatures was obtained as well as influence law of angle and curvature radius on stress at the elbow.
