基于不同材料长杆体稳定侵彻过程中破碎头部形状不同的事实,计算了两种初始头部形状相同但在稳定侵彻过程中破碎头部形状不同的杆体所受阻力,并基于此阻力求得对应头部形状的长杆体的侵彻深度,侵深值符合对应实验结果。阻力和侵深的结果比较表明,破碎头部形状尖锐的杆体侵彻效率高于较钝头部形状的杆体。 Based on the fact that the shapes of the broken heads are different during the steady penetration process of the long rods of different materials, the resistances of the two kinds of rods with the same shape of the initial heads but different shapes of the broken heads during the steady penetration are calculated. Based on this resistance Corresponding to the shape of the head of the long rod penetration depth, in-depth values ​​correspond to the corresponding experimental results. The results of resistance and penetration show that the sharpened shank has a higher penetrating efficiency than the blunt shank.
