摘要

传统电磁轨道炮(EMRGs)采用c型电枢和长方体导轨。利用LS-Dyna的电磁-力学耦合分析，模拟了凹形电枢在锥形导轨间的滑动。与传统的EMRG相比，带有凹电枢的锥形导轨的洛伦兹力增加了30%，出口速度增加了22%。

Analysis of an Electromagnetic Railgun with Tapered Rails and Concave Armature using 3-D FEM

Conventional electromagnetic railguns (EMRGs) use a C-shaped armature and cuboid shaped rails. A concave armature sliding between tapered rails is simulated using the electromagnetic-mechanical coupled analyses of LS-Dyna. Compared to conventional EMRG, the tapered rails with a concave armature result in a 30% larger Lorentz force and a 22% greater exit velocity.
