Missile launching dynamic simulation based on variation model
-
摘要: 基于偏差模型的导弹发射动力学仿真是根据偏差来源建立相应的偏差模型,将偏差力、力矩与标准状态下的受力叠加得到导弹实际受力,再进行运动状态的求解.这种基于偏差模型的仿真系统既能够单独分析各项干扰因素对发射精度的影响,还能够综合多项干扰进行数值打靶模拟分析.针对某舰载倾斜发射导弹,仿真分析了发射臂振动、推力偏心、导轨不平、舰船运动等干扰因素对初始扰动的影响,并进行了5 000次数值打靶统计分析.在给定的干扰概率分布条件下,命中概率达到93.86%.Abstract: An alternative approach to establish missile launching dynamic simulation system based on variation model was presented. The variation models were built according to their respective original sources. The variation forces and moments were added to the standard ones. The resultant was employed to solve the state of motion. This simulation system based on variation model could be used to analyze the effect of each interfering element upon launching precision; and it also could be employed in numeric targeting experiment. This method was applied to some ship-based inclined launching missile. Including launcher vibration, propulsion eccentricity, track uneven and ship movement, the effects of these interfering elements upon the initial disturbances were discussed. A 5 000-time numeric targeting experiment was carried out. On specified distribution of the interference, the hitting probability was up to 93.86%.
