摘要
为实现大口径火炮输弹机构的轻量化和小型化,根据惯性输弹工作原理,采用以直线电机为核心的电磁输弹方式进行弹丸装填.针对短时间歇式的输弹工作特点,开展适用于输弹的高电负荷直线电机设计,以降低输弹机构的质量和体积.基于虚拟样机仿真建立电磁输弹机构动力学模型,并结合电机参数进行输弹动力学仿真,结果表明,在最大射角下以直线电机为核心的电磁输弹机构可使弹丸具备可靠的卡膛速度,且相比于常规电负荷输弹机构,高电负荷输弹机构的质量降低了58.9%,体积降低了53.6%.基于高电负荷直线电机的电磁输弹方式可为输弹机构轻量化和小型化设计提供参考.
Abstract
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.
