| 中文摘要: |
| 采用多物质ALE流固耦合算法,对柔性储液容器的入水问题进行了仿真研究。该方法可以方便地考虑多种流体同时与结构耦合。首先,通过模拟平板恒速入水试验,验证了该方法的有效性,并确定了空气的影响。进而,仿真分析了复合材料柔性容器入水时的动态响应行为,结果表明,底部"空气垫"及容器内空气对冲击载荷具有一定的缓冲作用,容器底部形状、储液量等因素也具有较大影响。仿真得到的响应规律为容器的优化设计提供了重要的理论参考。 |
| 英文摘要: |
| The water entry process of flexible fluid reservoir is simulated by fluid-structure coupling method based on Arbitrary Lagangian-Eulerian (ALE) multi-material formulation,which can easily consider the coupling between a variety of fluid and structure.The validity of the method was proved by simulating a plate impact onto water with constant speed,and the influence of air is also conformed.Then,the dynamic responses of the water entry of flexible reservoir were analyzed.The results indicate that air curtain under the bottom and the air at the top of the container have some buffer effect to the impact load,the shape of container bottom and the volume of the fluid reserved also have great influence.The simulation results can provide important theoretical references to the optimal design of the reservoir. |
