| 1. | The error analysis of fit method to underwater gun ' s projectile velocity 接口控制器状态机的分析 |
| 2. | Optical design and analysis of laser screen for projectile velocity measurement 大面积激光测速靶光学系统的设计与分析 |
| 3. | The penetration mechanism is ductile penetration . the failure models and penetration mechanism vary with the projectile velocity 对于钝头弹侵彻,靶板的破损形式和侵彻机理,随弹速的变化而不同。 |
| 4. | Under the condition of penetration by flat - ended projectiles , the noses of flat - ended projectiles keep integrity when the velocity is under the normal projectile velocity 当弹速处于亚弹速范围时,弹头都保持了完好,此时弹体也视为刚性弹。 |
| 5. | When the projectile velocity reaches to the normal projectile velocity , the projectiles fracture crushingly , the penetration process is similar to the process penetrated by long rod projectile and can be divided into three processes that is crater process , steady penetration process and plugging process 当弹速达到常规弹速后,弹体发生粉碎性破坏,此时侵彻过程类似于长杆弹侵彻,侵彻过程可分为开坑阶段、定常侵彻阶段和剪切冲塞阶段。 |
| 6. | In the paper , the projectile pushing process on firing is analyzed . the quantitative computational model of the projectile velocity to gun bore wear is built . finally , taking the 120mm gun for example , the relation of projectile velocity to gun bore wear is calculated , the phenomenon of trajectory peak is analyzed 分析了射击时弹丸挤进过程,建立了弹丸初速下降量与炮膛内膛磨损量计算模型,并以某火炮为实例计算了该炮弹丸初速下降量与炮膛内膛磨损量之间变化关系,分析了弹道峰现象,为身管寿命预测提供理论依据。 |
