探测器成功附着在小天体表面是进行取样操作的前提条件,本文对三种附着方案:接触反弹短期着陆方案、盘旋附着方案和长期着陆方案进行了分析,列举了适用于接触反弹短期着陆方案和盘旋附着方案取样方法;对于长期着陆方案,分析了三种可行的缓冲器工作原理、结构组成及其特点,包括压缩吸能缓冲器、机械弹簧缓冲器和电磁阻尼缓冲器;此外还介绍了四种锚定机构的结构原理和特点。 The successful attachment of the detector to the surface of small celestial bodies is a prerequisite for sampling operation. In this paper, the three attachment schemes: contact-bounce short-term landing scheme, spiral attachment scheme and long-term landing scheme are analyzed. For the long-term landing scheme, the working principle, structure and characteristics of three kinds of bumpers were analyzed, including compression energy absorber, mechanical spring damper and electromagnetic damping bumper. In addition, the four Structure of the anchor mechanism principle and characteristics.
