| 摘 要： | 参考压力容器设计标准，针对某实验用球形爆炸容器进行了开孔补强设计，对容器开孔处等效应变随接管壁厚、补强圈尺寸的变化规律进行了数值计算，确定了“5/3倍球壳厚度的接管”配合“与球壳等厚度、张角10°的补强圈”的开孔补强设计方案。并对数值计算结果和补强设计进行了实验验证。

| Abstract: | Reinforcing design for the opening on a certain experiment-used spherical explosive containment vessel was carried out referring to the pressure vessel code GB150-2011. The relationships between the effective plastic strain around the opening and the geometrical parameters of the nozzle and the reinforcing ring were investigated by numerical simulation. And a reinforcing scheme was proposed which included a nozzle with the wall thickness equal to 5/3 times of the wall thickness of the main spherical shell and a 10°-reinforcing ring with the same thickness to the main spherical shell wall. Experiments were performed to validate the reliability of the simulation results and the rationality of the reinforcing scheme. |
