根据 ASME 标准，法兰刚度变化可由法兰转角反映。对某硫化罐进行分析，利用 ANSYS 有限元软件进行有限元计算，对封头法兰端面定义路径并由路径上点位移换算成路径转角。通过改变尺寸参数，最终得到封头法兰端面不同位置刚度变化规律并指出硫化罐端盖部分易发生泄漏位置。

According to the ASME standard, the change of stiffness of flange can be reflected by the flange deflection angle. In this paper, the finite element computation of a vulcanizing boiler was carried out by using the finite element software ANSYS, the path on the end of head flange was defined, and point displacement on the path was converted into a path deflection angle. By changing the size parameter, change rule of rigidity of the end of head flange in different position was obtained, and the easy leakage location was pointed out.
