Abstract: According to the technical parameters of existing throwing device, the current development of thro- wing device is firstly introduced, a new method is also put forward by using electromagnetic force for the throwing device＇s power. By analying three classical methods of electromagnetic emission technique, the coil electromagnetic emission method is applied to the design of electromagnetic throwing device＇s structure. At last, by using the soft- ware COMSOL Multiphysics, the three basic structural parameters of electromagnetic throwing device are simulated and analysed, namely, wall thickness of projectile, aperture of projectile and the initial launch position of projectile. The structure set of electromagnetic throwing device is optimized.

Key words: throwing device, electromagnetic emission technique, simulation in finite element, structure parameter
