基于过载信息的侵深确定方法数值研究

The Numerical Study on Penetration Depth Confirmation Based on Overload Information

为了研究侵彻深度的有效确定方法,利用仿真软件对动能弹侵彻混凝土厚靶进行仿真,通过对网格的有效控制、靶板材料失效模式的选择以及弹体的合理分割,获取了与实验基本吻合的过载特性。进一步对信息进行滤波以及积分处理,所得结果与仿真结果符合,说明此方法合理有效,能为侵彻深度确定方法的实现提供依据。

In order to study an effective confirmation method of penetration depth,the penetration through thick concrete was simulated with simulation software,the overload character was obtained through effective mesh control,failure mode choice of target material and reasonable projectile decomposition,the overload information was filtered and integrated,the result conformed with the simulation curve.This method was proved to be reasonable and effective to provide the basis for penetration depth confirmation.
