仿真分析三种射流形态对移动靶板的侵彻

Numerical Simulation of Penetration of Three Types of Shaped Charge Jet in Moving Oblique Target

为了分析3种射流形态对移动靶板的侵彻,利用ANSYS/LS-DYNA软件建立3种装药结构的战斗部模型,并分别进行数值模拟。结果表明,金属射流对移动靶的穿深明显,但是无法保证其射流的完整性;自锻破片对移动靶的开坑效果不错,但是其穿深无法达到作战指标;杆式射流能满足一定的穿深,且射流在侵彻过程中,几乎保持相对完整的射流形态。3种射流形态对移动靶板的侵彻,杆式射流优于金属射流和自锻破片。

In order to analyze penetration of three types of shaped charge jet in moving oblique target,the ANSYS / LS-DYNA software was used to build armor warhead＇s model. By a series of numerical simulation,the results show that the JET penetrated obviously into moving oblique target but could not guarantee the stability,the EFP cratered obviously on it but could not penetrate through it,JPC penetrated obviously it and could guarantee the stability. In conclusion,the penetration of JPC is better than the other two types of shaped charge jet in moving oblique target.
