摘要:
针对弹体斜侵彻弹道发生偏转的问题,建立了战斗部侵彻多层混凝土靶的计算模型,计算了攻角-4°~4°和着角0°~30°范围的侵彻弹道轨迹和弹道参数;讨论了攻角、着角对弹道偏转的影响规律,并通过多层靶的侵彻实验,验证了计算模型的正确性。结果表明,攻角和着角都会使弹道发生偏转,当攻角引起的弹道偏转与着角引起的偏转方向相反时,就会抑制侵彻弹道的偏转;当二者引起偏转的方向相同时,就会激化弹道的偏转;当着角与攻角方向相反时,若着角与攻角的数值大小满足5~10倍的关系,则可能使侵彻弹道偏移位移达到该着角条件下的最小值。
Abstract:
Aiming at the deflection problem of oblique penetration of the projectile, the calculation model of warhead penetration into multil-layer concrete trajectory was established. The penetration ballistic trajectory and ballistic parameters in the range of attack angle of -4°-4° and impact angle of 0°-30° were calculated. The influence factors of the penetration trajectory of concrete trajectory were studied. The influence law of attack angle and impact angle on ballistic deflection is discussed. Through penetration experiment of multil-layer traget, the correctness of calculation model was verified. The results show that the attack angle and impact angle make ballistic occur deflection, when the ballistic deflection caused by attack angle is opposite to the deflection direction caused by the impact angle, the deflection of the penetration trajectory will be suppressed.When the two cause the same deflection in the direction, the deflection of ballistic will be intensified. When the attack angle is opposite to the direction of the impact angle, if the magnitude of impact angle and attack angle meets the relationship of 5-10 times, it can make the displacement of ballistic trajectory reach the minimum under the impact angle condition.
