摘要
该文分析了几种u～V_j关系,简述了P～t实验方法,测量了铝、45~#钢和装甲钢三种靶材的P～t数据,通过处理得到了u～V_j关系曲线.经分析发现该曲线近于一条以不可压缩流体线为渐近线的双曲线,从而得到了u～V_j关系.还用最小二乘法将45~#钢的u～V_j关系处理成V_j的三次多项式,更便于用来计算大炸高下颗粒射流的侵彻深度.
In this paper,some different types of u～V_j(penetration velocity and jet ve-locity) relation is analysed.The P～t (penetration depth and time) experimentalmethod is briefly presented.The P～t data for three target materials:aluminium,steel45~# and armour steel are measured.The u～V_j relation curve is obtained by data re-duction.It is found by analysis that the u～V_j relation curve approximates to a hyper-bola of incompressible fluid,and thus the u～V_j relation is obtained.The u～V_j relation for steel 45~# is still reduced as V_j cubed polynomial by a least square method.So that penetration depth of particle jets at a large stand-off can be computed conve-niently.
