【摘要】：目的驗證SPH方法在流固耦合問題上的適用性。方法采用SPH方法(光滑粒子流體動力學(xué)方法)模擬無人機油箱抗沖擊過程,并與采用CEL方法(耦合歐拉-拉格朗日方法)模擬得到的結(jié)果進行對比。結(jié)果 2種模擬方法得到的燃油晃蕩情況、油箱應(yīng)力分布及地面支反力結(jié)果接近。結(jié)論 SPH方法在流固耦合問題上是適用的。
[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.
