双闸板防喷器主壳体的有限元强度分析

Using limited element to analize the strength of BOP casing with twin-ram block

为便于分析 ,简化了双闸板防喷器的结构。在额定工作压力和静液压试验压力 2种情况下 ,采用ANSYS分析软件对双闸板防喷器承压主壳体进行了有限元分析计算 ,证明有高应力区。按照ASME应力分析法分析其应力类别及应力组合 。

The structure is simplified in order for easy analysis.ANSYS is adopted to do analytical calculation for the BOP casing with twin-ram block under two cases of rated working pressure and static hydraulic tests. The tests show higher strain zone existing. It proves that the design is safe according to ASME strain analysis of the cassification of strain and the combination of strain.
