| 摘 要： | 对一碟形封头大开孔接管进行了三维和轴对称有限元应力分析，研究了接管区应力状况的影响因素。计算表明，可将偏置大开孔接管的空间问题适当转化为轴对称问题进行应力分析，使复杂问题简单化。

| Abstract: | Stresses in a torispherical head with large diameter nozzle are analyzed by three dimensional and axisymmetrical finite element method,the influence factors for stresses in nozzle's region are researchedThe calculation results show that the special problem for noncentral located large diameter nozzle can be properly changed into axisymmetrical problem, and then the stress analysis will be carryed on easily |
