摘要
利用飞散物在运动过程中所受到的空气阻力和重力建立飞散物运动方程,用高速摄影仪拍摄了烟幕爆炸成烟过程,并用实验结果求出了相关系数,校正了模型。结果发现空气阻力对烟幕成型有明显的影响。
The locus equation for the pellet＇s shiver of smoke projectile was established by using the air friction and the gravitation, and the solving process of equation was presented. The exploding process of smoke projectile was shot by a high speed camera. Test data were used to obtain related coefficients, and the mathematical model was modified further. The results illustrate that air friction effect on the flying locus of shiver is significant.
