摘　　要：为研究PTFE/Al(质量比73.5/26.5)含能材料在冲击载荷下的温度变化规律,运用ANSYS-AUTODYN软件对其以不同速度侵彻45#钢靶过程中的温度变化进行数值模拟。通过对所建立观测点的温度变化及单元变形情况的分析,表明在侵彻过程中,随破片侵彻速度的增大,含能材料的温升呈增大趋势。数值模拟还表明当速度低于1200m/s时含能材料的温度最高值在破片头部,高于此速度的含能材料温度最高值在中部。结合相关文献验证了模拟的合理性。To study the temperature variation of Polytetrafluorethylene/A1 （ mass ratio 73.5/ 26. 5 ）energetic reactive material under impact loads, using the ANSYS-AUTODYN numeri- cal simulation is conducted for it temperature changes when penetrating 45 steel target. Through the analysis of the temperature change which occured on the gauge, it is shown that, with the increase of penetrating velocity, the temperature of energetic material nolinear rises. Numerical simulation also shows that, when the velocity is lower than 1200m/s, the maximum temperature of energetic materials is in the head, when the velocity is higher than that, the maximum temperature appears in the middle. The simulation result is testified to agree with literature.
