| The defense of weapons systems,which has a long history, is a major issue related to the national security. As a new type of weapon armor technology, Active Electromagnetic Armor, which is based on Electromagnetic Launch technology progress, can significantly improve the defense capabilities of modern weapons systems. It has changed the concepts of weapons armor from passive defense to active defense. Compared with the conventional defensive mode, it has more superiorities.This paper firstly discussed the development and the present situation of Active Electromagnetic Armor and Electromagnetic Launch technology and expounded the working principles and basic model.This paper preset the basic model of Active Electromagnetic Armor, and according to the basic model, constructed the electric circuit and mathematical model. Then it calculated the required parameters, by using the basic electromagnetic theory and finite element software, obtained the required function of inductance and inductance gradient with respect to the position between the project and the driver coil, and calculated different materials.A dynamic system simulation software, Sinmulink, was used for modeling and simulation for Active Electromagnetic Armor. The factors that affected the speed of the projectile, such as the quality of projectile, the loop resistance, the initial charge voltage of energy storage capacitor, were analyzed and determined. The author obtained the condition of induced current distribution, the process of speed changing and distance of the projectile.Finally, based on the above research, the preliminary design of the Active Electromagnetic Armor model was completed and a simulation experiment system was finished. A simulation test was done by the simulation experiment system. The test results showed that the model works elementary agree with the simulation analysis results. All the research works provides a foundation for the further research work on Active Electromagnetic Armor. |
