摘要

Launch mechnism of coaxial induction coil launcher (CICL) is investigated based on the theoretical analysis of the armature's emf and its effect. The distributions of J in the armature for the given conditions of the dynamic operation and of eddy field are compared, which verifies the correctness of theoretical analysis. In addition, the influences of the armature's motion effect on the accelerative performance of CICL are researched by means of the method of finite element analysis. Researches show that the directions of Je and Jv are opposite in the early launch process. Je has acceleractive function for the armature in early operation process of CICL, and Jv has deceleraction function for the armature. Only Je>Jv, the armature can be accelerated. When Je
