Simulation analysis on stress field in induction coil launcher

The induction coil launcher is one kind of devices that can push forward the armature with the electromagnetic energy. In the course of emission, the drive coil and armature will suffer very big reacting force, so they may be ruptured or destroyed which affect the normal work of the whole induction coil launcher. It is very complex to analyze the generation and affection course of the stress in the induction coil launcher and it is also difficult to calculate. So, the paper uses finite element method to analyze the stress in the induction coil launcher. In the course of calculation, inherent stress, electromagnetic force stress and temperature stress are considered. At last, stress distribution of induction coil launcher is obtained by calculation.
