摘要
利用伞-弹系统动力学模型,从工程应用的角度出发,分析了阵风小扰动作用下,子弹姿态的运动特性,并以此为基础给出了末修子弹弹下点的计算模型.该模型的数值仿真结果与试验数据吻合良好.在导引头与弹体捷联的情况下,有效解决了弹体晃动时子弹相对跑道位置关系的确定问题,从而确保子弹对跑道有较高的命中精度.
The dynamics model of parachute-munition system is used to analyze the motion characters of submunition under the effect of wind gust, and the calculation model of projective point is presented. The computation result is the same as experimental data. This model is effective to resolve the relative position problem between runway and projective point when there is swaying for submunition with strap-down detector. A high hitting accuracy to runway for terminal correction submunition can be ensured.
