摘　　要：两栖火炮水上射击稳定性是一个涉及两种流场与两栖火炮相互作用的复杂问题。此前的研究往往将该问题中的流场作用简化为弹簧-扭簧系统,这样的简化模型会导致两栖火炮水上射击稳定性的预测精确度不足。文章通过两相流流固耦合方法详细研究了两栖火炮受到海面风浪作用产生的摇荡。仿真结果表明,两栖火炮在3、4级风浪环境中具有较好的稳定性,同等级风浪环境下不同的车体朝向角将对两栖火炮稳定性产生较大影响。Firing stability of amphibious artillery on water is a complicated problem involving the interaction between two kinds of flow fields and amphibious artillery.Previous studies have often simplified the flow field action in this problem to the spring-torsion spring system,but such a simplified model is not accurate enough to predict the firing stability of amphibious artillery on water.The oscillation of amphibious artillery subjected to sea wind and waves is studied in detail by the two-phase fluid-structure interaction method.The simulation results show that the amphibious artillery has good stability in the environment of third and fourth level waves,and the different orientation angles of the vehicle body will have a great influence on the firing stability of the amphibious artillery.
