摘要

摘要: 月球着陆器软着陆地点选择及安全着陆实现是探月二期的关键问题.采用不考虑着陆器着陆过程中发动机控制、着陆姿态控制和动力学性能,在计算机上依据低精度月面数据和已有月面典型地形特征分布/形状模型仿真生成高精度着陆区域;根据着陆器的结构尺寸和着陆安全要求对每个安全参数进行计算、比较、判断得到单次着陆安全性,利用蒙特卡洛方法计算多次在仿真地形上的着陆安全概率.试验结果表明:采用这种方法时,着陆器的结构尺寸相同分析结果才有意义.在计算机上仿真生成着陆区域、设置着陆器结构尺寸和安全参数,使其可以用于地面系统的仿真实验,也可在月面软着陆过程中实时分析选定区域的着陆安全概率.

Abstract: In the lunar exploration program Ⅱ, the lunar lander to a safelanding site selection and realize safelanding is the key issues. Without considering engine control, attitude control and dynamic property, a high-definition landing territory was simulated on computer based on the low-definition data and known characteristic models of lunar surface. One times landing security can be obtained by computing and analyzing lander profiles and landing safety requirement. The landing safety possibility of this terrain can be obtained by computing many times landing only under the condition of same lander profiles. The landing territory, lander profile and safety parameters were simulated on computer by this method can be applied to both ground simulation experiments and real-timely analyzing possibility of landing safety during soft landing on the lunar surface.
