“嫦娥三号”着陆器于2013年12月14日通过着陆缓冲机构在月面稳定着陆，表明中国已经突破并掌握了地外天体表面着陆缓冲技术，包括适合地外星体表面环境的缓冲方法、着陆缓冲机构设计方法和地面试验验证方法等。文章介绍了着陆缓冲方法的基本要求，对铝蜂窝缓冲特点进行了研究，提出了着陆缓冲机构关键几何参数确定及缓冲能力设计方法。此外，文章还介绍了着陆缓冲机构地面试验的主要验证项目和验证方案。这些研究成果不仅可以应用到未来火星等目标星体的着陆缓冲，而且在民用技术如桥梁的撞击防护、电梯抗坠毁及爆炸防护等领域中也具有十分广阔的应用前景。了解这些研究成果对于后续深空软着陆探测及相关民用技术的发展具有重要的意义。

On Dec. 14th 2013, Chang’e-3 lander successfully and steadily landed on the moon surface with its landing gear systems. It indicates China has demonstrably mastered the safe soft-landing technology on the moon and other planets. This technology involves attenuation methods in the environment of the celestial body surface, system design of the landing gear and ground test method. In this paper, common impact attenuation methods are introduced and a further study on an impact attenuation using aluminum honeycomb is performed. The process of determining key geometrical parameters of the landing gear and design method of attenuation capability is presented. The items and methods of ground test are also introduced in this paper. The achievements can be widely applied into the future landing on the Mars, as well as the civilian field like impact protection of bridges, crash prevention for elevators and safeguard against explosion, etc. They are valuable for the following deep space exploration and civilian technology progress.
