摘要
本文采用有限单元法对带有等径大开孔的压力混合器进行了应力分析，并在此基础上提出了检验要求。计算表明，只要保证制造质量，加强检验，等径大开孔结构是安全可用的。
The stress analysis of the pressurized mixer with two large openings with the same diameters was carried out by use of the finite element method. The corresponding inspection requirements were, then, built on the basis of the analysis. It has been proved that the structure with the large openings with the same diameter is safe if the fabrication and inspection can meet the quality requirements.
