【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。
[Abstract]:Objective to verify the applicability of the SPH method on the fluid solid coupling problem. Method using the SPH method (smooth particle fluid dynamics method) to simulate the anti impact process of the UAV oil tank, and compare the results with the results obtained by the CEL method (coupled Euler Lagrange method). Results the oil sloshing conditions obtained by the 2 simulation methods and the oil tank should be obtained. The force distribution and the ground reaction force are close to each other. Conclusion the SPH method is applicable to the fluid solid coupling problem.
