摘　　要：为研究大口径转管机枪在轻型三脚架上射击时的射击密集度随方位射角的变化规律,建立了具有不同方位射角的转管机枪系统刚柔耦合发射动力学模型,对机枪系统的射击动力学特性进行了仿真计算,分析了机枪系统不同方位射角射击时三脚架中柔性部件的弹性变形情况。利用动力学仿真得到膛口响应,计算了转管机枪以5个不同方位射角射击时的射击密集度。结果对比表明,转管机枪在轻型三脚架上射击时,随着方位射角的增大,射击稳定性变差,方位射角超过一定范围射击密集度下降明显,且左右射击时转管机枪系统振动具有不对称性。分析结果为转管机枪系统改进三脚枪架提供了参考。To study the influence of the attitude angle on the fire density of the gatling gun shooting on a light tripod,a rigid-flexible multi-body launch dynamics model with different attitude angles was established.Dynamic performance of this weapon system was simulated,and the elastic deformations of the flexible components of light tripod were analyzed.Fire density of gatling gun with five attitude angles were calculated based on muzzles response.The results show that the increase of the attitude angle causes the reduction of firing stability,and fire density sig-nificantly decreases while the attitude angle exceeds a certain range,and the vibration of this weapon system with opposite attitude angles is asymmetric.The results offer reference for improving the tripod for gatling gun system.
