摘要
针对在弹道修正引信研制过程中靶场试验成本高、周期长的不足,研制了弹道修正引信修正弹道视景仿真系统。该系统以火箭增程迫弹为研究背景,建立了火箭增程迫弹的6D弹道模型,利用蒙特卡洛法在引起弹丸落点散布的误差源上加上随机误差,运用龙格-库塔法不断解算弹道,再由基于STK的视景仿真子系统形象地给出弹丸飞行过程。结果表明,该系统仿真结果能较好地和实际靶场试验结果吻合,又能形象逼真地显示弹丸飞行过程。
Aiming at the range test with the shortage of the high cost and long period in the developing of trajectory correction fuze, the correct trajectory visual simulation system for the trajectory correction fuze was developed. Rocket-Assisted Mortar Projetliles was the study background of the system. 6D trajectory model was established. The random error was added to the error source leading to bullets landing distribution by using Monte Carlo method and the trajectory was continuously calculated using Runge-Kutta method. The bullets flight process was visually given based on STK visual simulation sub-system. The results indicate that the simulation results of the system are in good agreement with the range test results and show vividly the bullets flight process.
