摘要
电枢是电磁轨道发射器的关键部件,但以往对电感梯度的研究认为电枢距离炮尾部无穷远,忽略了电枢对导轨电感梯度的影响.为此,首先分别建立电磁轨道发射器的二维和三维模型,对比分析了无电枢部分导轨的电感梯度和电枢附近部分导轨电感梯度之间的差异;然后,基于有电枢的电磁轨道发射器三维模型,探究了U形电枢尺寸对电磁轨道发射装置电感梯度的影响.研究结果表明:随着导轨宽度,导轨间距,导轨厚度的增加,无电枢部分导轨的电感梯度和电枢附近部分导轨电感梯度之间的误差均逐渐增加;随着两种电枢宽度的增加,电磁轨道发射器电感梯度呈减小趋势,但变化量较小.
Abstract
Armature is a key component of the electromagnetic rail launcher,but previous studies on the inductance gradient consider the armature to be infinitely far from the tail of the railgun,ignoring the influence of the armature on the inductance gradient of the rails.Therefore,a 2-dimensional and a 3-dimensional model of electromagnetic rail launcher were respectively established so as to compare and analyze the difference between the inductance gradient of the rails without armature and the in-ductance gradient of the rails near the armature.The effect of the U-shaped armature size on the in-ductance gradient of the electromagnetic rail launcher was also investigated based on the 3D model of the electromagnetic rail launcher with armature.The results of study show that with the increase of the rail width,rail spacing,and rail thickness,the errors between the inductance gradient of the rails without armature and the inductance gradient of the rails near the armature are gradually increased,and the increase of two armature widths,the inductance gradient of the electromagnetic rail launcher tends to decrease,but the amount of change is not significant.
