【摘要】 基于6自由度弹道方程,采用符合误差因素分布特征的随机数,运用蒙特卡罗方法建立炮射子母弹定时开舱高度散布仿真预测模型。以某155 mm口径火炮为例,分别得到了最大射程、最大射程2/3处、最大射程1/2处和最大射程1/3处定时开舱高度散布的仿真数值。结果表明:以最大射程、最大射程2/3的射程射击时,开舱高度散布受纵风影响较大,而最大射程1/2、1/3处,装定时间散布是影响开舱高度散布的主要因素;配定时开舱引信的炮射子母弹不适合以最大射程攻击目标。更多还原

【Abstract】 The 6-DOF trajectory equation were applied,and the simulation predicition model for dispersion of opening height of gun launched submunition carrier projectile was established by using Monte-Carlo method and applying random number series according to the feature of error factor.The corresponding dispersion simulation values under one-third firing-range,a half firing-range,two-thirds firing-range and maximum firing-range were obtained taking a 155 mm caliber gun for a numerical example.The result shows that the maximum firing-range and two-thirds firing-range vertical dispersion of opening height is influenced greatly by longitudinal wind.And the spread in timer time has a great impact on the vertical dispersion under one-third firing-range and a half firing-range.The gun launched submunition carrier projectile is unfit to attack target with the maximum firing-range.更多还原
