Landing stability analysis of the lunar lander based on Monte Carlo approach

  • 摘要: 为了验证月球探测器的软着陆性能,建立了月球探测器着陆过程多体动力学仿真分析模型.由于探测器着陆地点及初始着陆条件的不确定性,采用蒙特卡罗法对探测器的着陆稳定性进行了研究.为了提高蒙特卡罗模拟的效率,采用了基于均值估计相对误差的蒙特卡罗模拟终止准则,从而在保证精度的前提下减少计算成本.通过着陆仿真试验,获得了探测器在给定坡度的月面上着陆时,各着陆性能参数的分布均值、方差及相应的置信区间等统计学结果,并计算了探测器安全着陆的可靠度.
