摘　　要：为改进原来杆条斜穿甲方程的缺陷与不足,正确反映实际情况中杆条剩余速度、剩余质量与攻角、着角之间的关系。根据战术弹道导弹的目标特点,从动能杆条的终点穿甲机理出发,在参考原始弹道研究的破片穿甲方程和动能杆条正穿甲方程以及修正的杆条斜穿甲方程基础上,构造了模型简化过程,建立了新的修正的动能杆条斜穿甲带攻角穿甲计算模型。通过数值仿真,得到了杆条剩余速度、剩余质量与攻角、着角之间的变化规律,并且数值模拟结果与文献试验结果较为吻合,验证了模型的准确性。说明了新建立的穿甲模型的正确性,其更适用于实际情况。In order to improve earlier KE-rod slanting THOR armor-piercing model and correctly reflect relationships, based on the ending point armor-piercing mechanism and the characteristic of TBM, a new corrected KE-rod slanting THOR armor-piercing calculating model with angle of attack was built based on original BRL pieces armor-piercing THOR equation and KE-rod THOR armor-piercing model and KE-rod slanting THOR armor-piercing model. According to simulation, changing law for residual velocity, residual quality of rod and angle of attack, angle of entry was got, and veracity was checked by comparing simulation with testing result. It shows validity of the new model which is more suitable for actual situation.
