| 摘要: |
| 通过对内置式耐压液舱中实肋板开孔拓扑优化设计后的强度和稳定性分析发现，对于周向范围为162°的内置式耐压液舱，实肋板在中内龙骨附近开孔较优。实肋板开孔后对于其本身的稳定性影响不大，但MISES应力会有所变化；实肋板开孔后，液舱结构的稳定性会稍微降低，后期在进行液舱结构设计时要考虑是否加强。 |

| Abstract: |
| By analyzing the strength and the stability after the topological optimization design of the open-hole topology of the solid floor in the inner pressure-resistant tank, it is found that the solid floor opened near the inner keel is better for the inner pressure-resistant tank with a circumferential range of 162°. It has little effect on its own stability for the opening of the solid floor, but the stress of the MIMES will change. The stability of the liquid tank structure will be slightly reduced when the hole is opened. So, the structure requires strengthening when designing the liquid tank structure in the later stage. |
