月面软着陆探测器地面力学试验方法研究

月面软着陆探测器的主要任务是携带有效载荷实现在月球表面的安全着陆,其经历的主要过程包括发射段、地月转移段、近月制动段、环月段、着陆段和月面工作段。软着陆探测器面临的月球环境比近地轨道卫星复杂得多。为提高软着陆探测器系统的可靠性,必须进行充分的地面试验,验证软着陆探测器的设计合理性。文章分析了月球软着陆探测器在各飞行过程中面临的力学环境,分析了力学环境对探测器系统的影响及作用效果,提出软着陆探测器需完成的地面力学试验项目,设计相应的试验方法,并给出确定试验量级的基本原则。

Study on Methods for Lunar Lander Dynamical Experimentations

The most important mission goal of the lunar lander is to land on lunar surface safely with payloads and a lunar rover.The whole mission process is different from the satellite on near-earth orbit,thus the dynamic condition which the lunar lander will experience is totally different.For the lunar lander,the dynamical experimentations are essential.In this paper,the dynamic condition which the lunar lander will faced in flight process is analyzed.Based on the analysis results,the environmental effects on the spacecraft system are researched.Details,methodologies and principles of the dynamical experimentations are presented.
