Firing Stability Analysis of Amphibious Artillery on Water Based on Two-Phase Fluid-Structure Interaction Method
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 am-phibious 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 stabil-ity 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.
