摘　　要：对侵彻火箭弹的引信中发火决策方式进行总结。利用有限元动力学仿真软件Ls-Dyna完成对火箭弹以不同角度斜侵彻复杂目标过程中遇到墙角时的动力学仿真。根据仿真得到的位移,加速度数据,对单传感器的火箭弹侵彻引信进行讨论,发现其中存在的一些问题,如无法分辨水平和竖直目标,无法探测跳弹等情况,即墙角效应对于侵彻引信的影响,同时根据仿真数据分析了引信中利用两个传感器测量的优势。The fire decision-making mode of the penetration fuze in rocket bombs are summarized. Finite element dynamic simulation software Ls-Dyna was used for completing the dynamic simulations of the processes in which rockets with different angles penetrate into the complex targets. According to the displacement and acceleration data obtained during the simulation, the penetration fuze of rockets with one sensor is discussed. Some problems （such as ricochet cannot be detected, and vertical and horizontal targets cannot be recognized） existing in the penetration fuze were found. That is the influence of corner effect on the penetration fuze. The superiority of fuze with two sensors are analyzed according to the simulation data.
