The rail inductance gradient is an important parameter of the electromagnetic launcher. calculation its value for design launcher structure and predicting motion behavior armature. current research on analysis method mostly does not take into account effects size diffusion. This cannot describe dynamic characteristics, it results in a large error compared with actual launch. Therefore, paper fi...

When armature passes through the central plane of a driving coil in process reluctance launching, magnetic force will reverse and slow down speed. To overcome this problem, principle launcher is analyzed. Meanwhile, paper establishes finite element analysis model to calculate electromagnetic force, velocity, displacement other parameters while works. Based on simulation results, dynamic charact...

Abstract When the vehicle-mounted electromagnetic gun is launched, vehicle body subjected to strong arc reaction, magnetic field interference and shock wave phenomenon. By establishing external model of multi-tube launch chamber, protection characteristics launcher’s full-life counting device are studied, during analyzed by COMSOL software, distribution position selected. Then, based on shieldi...
