摘要
假定弹体为刚体 ,利用空腔膨胀理论计算了刚性弹丸垂直侵彻靶板时的侵彻阻力 ,并以卵形弹为例根据牛顿定律得到了只含有 2个无量纲参数的侵彻深度表达式 ,并与实验结果进行比较 ,二者吻合良好 .
Based on the cavity expansion, a formula of penetration resistance is obtained. Taking a ogive nose projectile as an example, a dimensionless formula is proposed to predict penetration depth into concrete target subjected to a normal impact of a rigid projectile according to Newton's second law. The proposed formula depends on two dimensionless parameters and the data calculated from the formula are in good agreement with the experiments.
