本文利用SAP 5程序对上海第一石油机械厂设计的防喷器壳体进行了强度分析。先将壳体作为轴对称旋转厚壳计算,然后对不符合轴对称条件的顶部螺栓孔区作局部细算,并将结果作了比较。
In this paper, the strength of the blowout preventer housing designed by Shanghai No. 1 Petroleum Machinery Factory was analyzed by SAP 5 program. First, the shell is calculated as an axisymmetric rotating thick shell, and then the top bolt hole area that does not meet the axisymmetric conditions is locally calculated, and the results are compared.
