| Abstract: | A study on water impact of recovery module was carried out by means of a simulation method.Three-dimensional finite element models were established.The space capsule with different velocity and different mass entering into the water are calculated.Through analyzing the results of simulation,it is found that the pressure peak value curve of slamming is in good agreement with experimental data and shown that the simulation study is feasible. |
