Abstract:
An equivalent circuit model of the magnetic flux compression generator is established.The armature expansion process of the helical magnetic flux compression generator is simulated by ALE algorithm of LS-DYNA.The armature expansion angle formed in different armature materials,armature dimension and stator dimension is obtained.The research results show that: in the similar explosives parameters and armature dimension,the aluminum armature expansion angle is bigger than the brass armature expansion angle,and the voltage generated in inductive load is bigger than that in the brass armature;the aluminum armature material can improve the equipment output voltage,and the brass armature material can enlarge the pulse width.The results provide necessary parameters for the theoretical computation of the output characteristic of the non-nuclear explosive magnetic flux compression generator and an important basis for designing reasonable geometrical armature figure.
