摘　　要：采用LS-DYNA有限元软件建立钨合金高速侵彻Q235钢板过程的有限元分析模型(FEM),获得钨合金弹头侵彻过程速度变化及钨合金弹头变形、损伤和破坏演变规律,系统研究钨合金性能对侵彻过程的影响,表明钨合金密度、屈服强度和失效应变对弹头侵彻速度和破坏方式有显著影响,而钨合金硬化参量和应变率敏感系数的影响相对较小。研究结果有助于加深钨合金侵彻过程的认识,同时为制备侵彻性能优异的钨合金也提供了理论依据。The finite element model（FEM） for tungsten alloy penetrating Q235 steel plate with a high speed has been built up by adopting LS-DYNA software,and the velocity and the evolution process of deformation,damage and failure for tungsten alloy projectiles during the penetrating process has been acquired.The effects of the properties of tungsten alloy on the penetrating process have been studied systematically.The result shows that the density,yield strength and fail strain have important effects on the velocity and failure,but the hardening parameter and the strain rate factor only have a minor effect.This study is helpful to the understanding of penetrating process of tungsten alloy,and a theory reference is also provided for making tungsten alloys with better penetrating properties.
