火星着陆技术是实现对火星探测的关键技术。文章通过对四面体着陆器展开过程进行深入研究,提出了一种应用于四面体火星着陆器扶正展开的方法,并对该方法进行了详细的分析和计算;通过火星着陆器扶正展开动力学的分析,提出了扶正展开系统的动作策略,对实现扶正展开的姿态确认进行了分析和设计;基于Hamilton法建立了扶正展开着陆器的动力学模型,对多姿态下扶正展开执行器的动力学特性进行了分析,获得了扶正及展开过程中的力矩特性,从而可以对翻转动作进行定量的分析,实现翻转能量的最小化。该研究对于火星着陆器的设计具有参考意义。
Mars landing technology is the key to Mars exploration. In this paper, through deep research on the unfolding process of tetrahedral lander, a method applied to the development of tetrahedral Mars lander is proposed, and the method is analyzed and calculated in detail. The kinematics of the lander Analyzed and put forward the strategy of strengthening the system to start the system, and analyzed and designed the confirmation of the posture of the righting. Based on the Hamilton method, the dynamic model of the progenitor was developed, and the dynamic characteristics of the actuator The torque characteristics in the process of righting and unfolding are obtained, which can be used to quantitatively analyze the turning movement and minimize the turning energy. This research has reference significance for the design of Mars lander.
