The article using the methods of combining numerical simulation, theoretical analysis with test to analyze the projectile's ballistic limit velocity for homogeneous steel plates under the condition of the 45° attack angle, in order to validate the rationality of the simulation model and the availability of the experiment method. Firstly, through simulation and the theoretical formula estimated the ballistic limit velocity for penetrating the homogeneous steel plates under the 45° attack angle. Then, contrast the results with engineering test. By comparison and analysis, it can be found that there was good consistency between the simulation, theoretical arithmetic results and the engineering test results. The article provided the effective data support and theoretical basis for similar researching in the future.
