The Theories and Application of Numerical Simulation with Smoothed Particle Hydrodynamics Method

摘要：

　　The Smoothed Particle Hydrodynamics (SPH) method is a very important method to resolve hypervelocity problems and the basic theory of SPH method is introduced here.Then the three dimensional hypervelocity impact problems are simulated by using the model of chair.The results of SPH analysis show that (SPH) method is a numerical calculation method to resolve hypervelocity problems without mesh model but the particle model must be getting to calculate and the program code is less than other method.By analysis the results of the simulation is reasonable and very similar to the test result.It can be concluded that the advantages of SPH demonstrated make it a good and an ideal method to simulate the impact problem and other problems.
