月球表面环境综合模拟系统的设想

相比于环绕地球飞行的卫星或载人飞船,探月航天器面临的空间环境更为复杂和严酷.月球表面的环境对登月飞船、月球车的环境适应性及可靠性提出了极为严格的要求.文章就月球表面综合环境模拟系统进行了初步的系统设计.该系统可实现月表尘埃、地形地貌、承载能力及摩擦效应、真空、温度交替变化等环境因素的综合模拟,可为登月飞船及月球车的设计、优化以及最终的系统验证提供试验平台.

The Conceptual Design of Lunar Surface Environment Simulation System

Compared with the satellites and manned spaceships circling the earth, the spacecraft for lunar exploration has to endure more complex and more rigorous environment. Especially, the lunar surface environment may cause very severe problems, thus should be considered carefully in the design of spacecrafts and lunar rovers. A conceptual design of lunar surface environment simulation system was proposed. Most of the environmental factors, including lunar dust, geography, the compressibility and frictional effect of lunar regolith, hard vacuum, temperature variation, can be simulated simultaneously. The system may serve as the test facility of spacecraft and rover design, optimization and verification.
