Abstract

Water-entry impact of air-launched AUV (AL-AUV) is considered as a timedepended strongly nonlinear fluid-structure Interaction phenomenon. Numerical modeling technique of AL-AUV on its initial water-entry impact is given by using the Multi-Material ALE-Lagrange coupling algorithm. The key aim is focused on the numerical modeling approach taken in detail to dealing with water-entry impact. Based upon this, water-entry impact loads and effect of fluid on the impact responses are also specially discussed. Numerical results show that the exact dynamic characteristics can be obtained in effect by modeling the appropriate water-entry numerical model and the right resolve method. It is helpful to the structure design and to analyze the later hydroballistics.
