摘要
电磁轨道发射装置在发射过程中存在后坐力,为研究其反后坐技术,该文结合某电磁轨道发射装置模型,建立了后坐运动微分方程,设计了两种反后坐装置方案,进行了发射装置在0°、35°和70°3种射角工况下分别采用两种反后坐装置方案时的后坐规律仿真计算,试验验证了仿真计算模型有效。对仿真计算结果进行对比分析,得出结论:对于具有大后坐部分质量和宽射角范围的电磁轨道发射装置,采用2套复进机和2套驻退机分别对称布置在身管的上下和左右两侧的反后坐装置方案,能够有效提高反后坐装置密封可靠性,避免后坐部分受到偏转力矩作用。
Electromagnetic rail launcher has recoil force in the process of launching.In order to study its recoil technology,based on the launching system of an electromagnetic rail launcher,the differential equation of recoil motion is established and two kinds of recoil device schemes are designed.The simulation calculation of recoil law of launching device with two kinds of recoil device schemes at three angles of attack of 0°,35°and 70°is completed,and the simulation model is validated by experiments.The simulation results are compared and analyzed.It is concluded that for the electromagnetic rail launcher with large recoil mass and wide firing angle range,the using of the recoil device with two counter-recoil mechanism and two recoil mechanism arranged symmetrically on both sides of barrel can effectively improve the sealing reliability of recoil device and avoid the effect of deflection moment on recoil parts.
