【摘要】 基于应力分析设计法的基本原理，给出了通过有限元法得到应力分量后进行应力分类和应力评定的方法。通过有限元计算得到汽包封头的温度场、应力场，确定了其危险截面，并应用应力分析设计法对汽包封头的强度进行了校核。更多还原

【Abstract】 Based on the basic rules of stress analysis design method and with the obtainment of thestress components by the finite element method, the way of stress classification and stress strength evaluation is put forward in this paper. The temperature field and stress field of drum head are obtained byFEM. The dangerous section of drum head was defined as well. By applying the stress analysis method,the strength of drum head was checked.更多还原
