| Abstract: | The Free Lagrangian Method Based on Taylor's Expansion is developed. A one dimensional hydrodynamic code is written according to this method. Both examples of the shock tube and impact of flyer on the target are simulated by this code. The results are in good accordance with that obtained by traditional Lagrangian difference code. |

| Keywords: | Taylor's expansion shock wave numerical simulation |
