| 摘 要： | 确定炮射云爆战斗部的抛射时间是完成炮射云爆弹研究的重要环节.文中用ANASYS仿真软件对母弹入地的姿态、受力情况以及战斗部抛射的三个阶段(母弹触地引信点燃、弹尾螺纹被剪子弹开始运动和子弹运动瞬间到抛射药燃完)进行了仿真分析.在此基础上,利用工程计算软件Matlab在相关假设的基础上对抛射过程进行了数值计算,得到了抛射时间与抛射力以及抛射瞬时速度的关系,通过分析计算获得了某型炮射云爆战斗部的抛射时间,验证了该抛射时间的合理性.

| Abstract: | Determine ejection time of gun-launched fuel air explosive(FAE) warhead is important for gun-launched FAE study.The ANASYS was used to simulate and analyze the munitions penetration posture,stress and three phases of warhead ejection(munitions impact and fuse ignition,screw thread of the shrapnel is nipped and the submunition begins to move,the duration of submunition momentary to powder burnt out).On the basis of these analyses,the ejecting course was calculated with Matlab based on related hypothesis.The ... |
