摘要

Multi-material ALE method was used to fluid-structure interaction dynamic analysis on water impact of three-dimensional elastic projectile, by the explicit formulation dynamic analysis finite element software LS-DYNA. The influences of key control parameters were discussed. Numerical simulation results indicate that, this model can solve the numerical computation difficulty originated from fluid great shape change in fluid-structure interaction dynamic analysis, and the water-gas interface is reasonable. Pressure applied from fluid on projectile is analyzed, important references for the design of projectile structure. Projectile attitude and position variety under different initial state is compared, which is helpful to design appropriate initial attitude in water impact of projectile.
