| 中文摘要: |
| 目的 验证SPH方法在流固耦合问题上的适用性。方法 采用SPH方法（光滑粒子流体动力学方法）模拟无人机油箱抗冲击过程，并与采用CEL方法（耦合欧拉-拉格朗日方法）模拟得到的结果进行对比。结果 2种模拟方法得到的燃油晃荡情况、油箱应力分布及地面支反力结果接近。结论 SPH方法在流固耦合问题上是适用的。 |
| 英文摘要: |
| It aims to prove that SPH method is suitable for fluid-structure coupling problems. UAV fuel tank impact process was simulated with SPH (smoothed particle hydrodynamics) method and CEL (coupled eulerian-lagrangian) method respectively. The simulating results with two methods were compared. Fuel fluctuation, stress distribution and ground reaction force of the two results were similar. In conclusion, SPH method is suitable for fluid-structure coupling problems. |
