应用 Ansys有限元分析软件 ,对汽包下降管部位进行了三维有限元应力分析 ,定量分析了管孔内转角形状对应力集中系数的影响。计算结果表明 ,圆角过渡的内转角形状有利于降低应力集中水平
Using Ansys finite element analysis software, the 3D finite element stress analysis of the descending pipe of the drum was carried out, and the influence of the corner shape of the pipe hole on the stress concentration factor was quantitatively analyzed. The calculation results show that the inner corner shape of fillet transition is helpful to reduce the stress concentration level
