Modeling and Analysis of Electromagnetic Railguns System

Railguns which are complex electromechanical systems applied in weapons make use of electric energy to promote the armatures and projectiles to a hypervelocity. The basic principles of railguns are introduced. Based on the analysis of the characteristics of circuit,kinematics and energy consumption of railguns,a mathematical model of the system using MATLAB is established. The current,armature velocity,energy input on railguns are computed under different inductance gradient. Different forms of energy consumption and the energy efficiency are analysed during the launch. It is concluded that under the certain power supply parameters,if the inductance gradient value is increased within a certain range,the current amplitude is reduced,but the muzzle energy and efficiency is improved significantly. The research has a certain reference value to electric application characteristics study of railguns.
