| Abstract: | The operation principle and equivalent circuit of electromagnetic railgun are analyzed, and model is built and simulated. The influence of main electric parameters and trigger time sequence of source modules on muzzle velocity is studied. Some principles of optimum design for electromagnetic railgun are presented to increase the muzzle velocity and extend the length of rail life synchronously by reducing the impact of current on rail, such as rational design the rail shape and selection of appropriate rail material in order to increase the inductance gradient and decrease the resistance gradient, regulation of pulse forming inductance and capacitor to decrease the peak value time, and increasing the peak value of current, capacitive storage power supply consist of modules triggered by time sequence control. |
