“…Xu Weidong [9] carried out a computational simulation analysis for small diameter armatures and investigated the through-flow capacity and firing rate of C-type armatures of different materials, and concluded that the size of the armature neck has a large influence on the through-flow capacity of the armature. However, the initial contact characteristics for the armature loading position were less studied, especially the influence of armature structure parameters [10][11][12][13][14] .…”

As a key component of an electromagnetic rail launcher, the armature plays a vital role in the performance of the electromagnetic launch. In order to solve the contact area and structural design problems of C-type armatures under large pulse current conditions, the material and initial contact state of a certain calibre C-type armature are studied, and the initial structural parameters of C-type armatures under 400kA through-current capacity and four times the calibre loading position constraints are analysed and calculated, together with the contact characteristics of armatures made of 6061-T6 and 7075-T6 aluminium alloys, to form At the same time, the parametric design of the C-type armature was carried out on the basis of the initial structural parameters, and the variation laws of contact stress, contact deformation, preload force and contact area were studied for different armature lengths, armature tail thickness, armature throat thickness and armature head height, with the encore law, contact area and plastic deformation stress as The structural dimensions of the C-type armature for a 400 kA pulse current are determined, providing a direction for the structural optimisation of subsequent large pulse current C-type armatures.
