Simulation and optimization of electromagnetic induction characteristic in chamber of coaxial solenoid′s barrel
摘要
Abstract
Since the induction magnetic field of close-coiled solenoid is difficult to penetrate the metal cylinder wall under the high frequency external excitation,the electromagnetic induction characteristic of the metal cylinder of electrified solenoid with different excitation types is deduced on the basis of Maxwell′s equations,and the electromagnetic simulation model of the barrel of coaxial solenoid is established by taking a certain gun barrel as the simulation example to perform the simulation analysis of the electromagnetic induction characteristic in the chamber at different excitation frequencies. The coil parameter and barrel parameter are taken as the design variables to optimize the electromagnetic induction characteristic in the chamber of coaxial solenoid′s barrel,so as to further improve the magnetic induction intensity in the chamber at AC excitation. The simulation results show that the magnetic induction intensity is exponentially decreased with the increase of the excitation frequency;under the same excitation conditions,the optimization of coil and barrel parameter can reduce the shielding effect of the metal barrel on external excitation source,so as to improve the equivalent magnetic field strength in the chamber.关键词
