摘要
研究了用 93W 10 5模拟弹以 14 0 0m/s左右的速度侵彻四种回火状态的 6 0 3、6 75、6 85钢装甲和弹体的破坏方式。研究过程发现 ,穿深、坑口和坑底直径都可以成为描述装甲钢抗弹性能的参数。另外坑口和坑底直径与材料抗弹性能有密切联系。研究中还发现 ,侵彻过程中钨合金穿甲弹发生了绝热剪切 ,绝热剪切产生的高温可以使钨发生融化并使装甲发生过烧。用钢穿甲弹进行实验 ,钢弹也出现绝热剪切 。
The damage patterns of armour steels and rod penetrators in the course of 93W105 simulated rod penetrators with 1?400m/s velocity penetrating into four kinds of tempered 603, 675 and 685 steels were researched. The results show that penetrating depth, diameter of crater mouth and crater end can all be used as the parameters for describing the ball-proof behavior of armour steels. The depth of craters in armour steels with good ball-proof behaviour is low, but the diameters of crater mouth and crater end are large, otherwise it is on the contrary. The research results show also that a adiabatic shear behavior appears in W-alloy penetrators during penetrating, and the high temperature because of adiabatic shearing makes W-alloy melt and armour plate overburn. The adiabatic shear behavior appears also in steel penetrators when steel penetrators are used. These demonstrate the main failure way of penetrators material during penetrating is adiabatic shearing.
