Soil continuous impact behavior of centrifuge throw-filling equipment is simulated using FEM-SPH (Finite Element Method & Smoothed Particle Hydrodynamics) coupling method. Centrifuge structural components are with Lagrangian finite elements and meshless smoothed particle is applied for soil model in numerical simulation. Continuous impact process of cohesionless soil reappears in FEM-SPH simulation result. Given soil impacting centrifuge hopper and soil box bottom at 5m/s, 10m/s speed respectively, stress distribution and equivalent impact load of centrifuge are gained in soil continuous impacting condition. The maximum stress is about 292MPa and on the cross section of centrifuge support device for soil 5m/s impacting hopper condition. Rubber layer cushion on soil box bottom may decrease impact loading amplitude when soil impacts box bottom at speed of 10m/s. Rubber layer can protect box structure from soil continuous impact damage. As FEM simulation is with high computational efficiency and SPH method is good way to describe structure large plastic deformation and damage, FEM-SPH coupling method can be applied to simulate soil-like material large deformation behavior. It contributes to improve numerical simulation’s fidelity and confidence coefficient.
