软着陆验证试验中月面特性模拟方法
|
摘要
月面特性的模拟是月面软着陆验证试验的重要设计因素。文章结合探测器的设计状态和试验需求,论述了月面特性模拟的具体要求;基于月面地形统计分布规律,实现了月面原始形貌的模拟;通过高程剔除设计和模块化组合设计,实现了对多种典型月貌的快速模拟;最后通过月表反射特性的模拟,全面满足了试验要求,并取得了良好的试验效果。文中所述的模拟方法可为我国后续行星表面探测器及着陆技术的验证提供借鉴。
The lunar terrain simulation is a key design procedure in the soft landing verification test. This paper firstly provides a detailed description of the lunar terrain simulation by incorporating the design states of the probe with the test requirements. The simulation of the pristine morphology of the lunar surface is carried out based on the statistical distribution of the lunar terrain; a rapid simulation of typical terrains is achieved by eliminating the height exceptional dots and with a modular assembly. The reflective properties of the lunar surface is also considered. The test shows that the above simulation method can comprehensively meet the test requirements, and provide reference data for China's subsequent verifications of the planetary probes and related landing technologies.
