Simulation of Electromagnetic Launch Type Tear Weapon System

Abstract:

In the process of tear the launch of weapon system, discharge voltage, capacitance, and the difference of Tear gas initial position, will affect the size of the tear gas exit velocity. In order to make the next step of the experiment platform ammunition exit velocity reach the expected target, we need to determine the appropriate size of those parameters. To a single induction coil launch unit as an example, using the Matlab software to establish the mathematical model of single stage induction coil launch unit, and then to the projectile export rate as the objective function, adopting axisymmetric coil magnetic field numerical calculation method and the differential equation of the forward difference method to solve the mathematical model to solve the problem, the simulation analysis of the discharge voltage, capacitance, and the Tear gas projectile from the initial position of the exit velocity, the influence of the discharge voltage, capacitance, and the Tear gas is obtained initial position relations with tear gas exit velocity curve, determine the size of the voltage, capacitance size, the size of the initial distance option.
