Research on Electromagnetic Ammunition Ramming Technology Based on High Electric Load Linear Motors
Based on the principle of inertial ammunition ramming,an electromagnetic ammunition ramming method using linear motors is employed to load the projectile,so as to reduce the weight and footprint of the ramming mechanism for large-caliber guns.As ammunition ramming is an intermittent process that involves a very short amount of time,high electric load linear motors suitable for the job is designed to reduce the mass and size of the ramming mechanism.A dynamic model of the electromag-netic ammunition ramming mechanism is established based on virtual prototype simulation,and dyna-mic simulation is carried out using motor design parameters.The results show that the electromagnetic ammunition ramming mechanism based on linear motors can give projectiles consistent seating velocities at maximum elevation.Compared with conventional electric load ammunition ramming mechanisms,the mass and size of the high electric load ammunition ramming mechanism are reduced by 58.9%and 53.6%respectively.Electromagnetic ammunition ramming technology based on high electric load linear motors provides a reference for weight and size reduction design of ramming mechanisms.
