电磁轨道炮反后坐装置研究
|
摘要
随着电磁轨道炮发射能级越来越大,发射装置后坐力也越来越大,为改善炮架受力,使用反后坐装置成为必要。本文以某电磁轨道炮为研究对象,建立了发射系统简化实体模型和动力学模型,在相同发射工况下,分别对采用3种不同类型反后坐装置的发射系统在0°和45°射角状态下的后坐复进运动规律进行仿真计算,得出在宽射角范围条件下,采用两复进机和两驻退机均匀对称布置方式的反后坐装置,反后坐综合效能更优的结论。本研究对大能量、宽射角电磁轨道炮的发射系统总体设计具有一定的参考价值。
With the increasing energy level of the electromagnetic rail gun, the recoil of the launcher is getting bigger and bigger. In order to improve the force of the carriage, it is necessary to use the recoil device. In this paper, an electromagnetic rail gun was taken as the research object, and the simplified model and dynamic model of launch system were established. Under the same launching conditions, the recoil law of the launching system with three different types of recoil mechanism at 0°and 45°elevating angle, was simulated respectively. It is concluded that under the condition of wide angle of fire,the comprehensive efficiency of the recoil mechanism with two reentry machine and two recoil machine in symmetrical arrangement is better than two others. This study has a certain reference value for the overall design of the launch system of the electromagnetic rail gun with large energy and wide angle of fire.
