| 摘 要： | 双层储液容器相比于单层储液容器在抗碰撞冲击方面有着更加良好的性能.采用多物质ALE有限元方法和流-固耦合均衡分区并行计算方法,模拟计算了单/双层储液容器在与地面碰撞冲击时储液容器的动态响应,仿真计算结果为双层储液容器的设计提供了参考依据.最后比较了坐标递归对分和流-固耦合均衡分区两种并行算法对并行效果的影响.结果表明,后者比前者有着更高的加速比和并行效率.

| Abstract: | Dual liquid-filled container has better performance than single liquid-filled container for crash problem.Mutil-material ALE method and fluid-structure interaction balance bisection method for parallel computing were used to numerically solve dynamic behavior of single/dual liquid-filled container during the impact with the ground,and the simulation result will provide importance reference for the design of dual liquid-filled container.Compared with the results through the recursive coordinate bisection method, the fluid-structure interaction balance bisection method has high speedup and parallel efficiency in solving fluid-structure interaction. |
