The invention discloses a coiling type stretching extraterrestrial celestial body landing mechanism and a design method thereof, and belongs to the technical field of machinery. Compared with a traditional landing mechanism, the landing mechanism not only can be stored in a smaller space before a spacecraft is launched, but also can be unfolded in the one-dimensional direction in the unfolding process, envelope of mechanism stretching movement is effectively reduced, and the space utilization rate is increased. Therefore, the space can be saved for one launching task, other extra load equipment can be installed, and the efficiency of the task is improved; the cross section size and the configuration of the coiled extension arm are improved, so that the weight is effectively reduced while the bearing capacity of the landing mechanism is ensured; the optimization result is obtained through a sequence planning method instead of manual modification of iterative design, and the effectiveness of the result can be ensured. Compared with a traditional coiled extension arm, the bending resistance is improved, it is guaranteed that the landing mechanism can bear landing impact in the landing stage, and safe landing of the detector is achieved.
一种盘绕式伸展地外天体着陆机构及其设计方法,属于机械技术领域。与传统的着陆机构相比,本发明不仅在航天器发射前阶段可收纳于更小的空间内,同时在展开过程中能够沿一维方向进行展开,有效减少了机构伸展运动的包络,提升空间利用率。这使得本发明可为一次发射任务节省空间并安装其他额外载荷设备,提高任务的效能;且本发明在盘绕式伸展臂的构件截面尺寸和构型两个方面均进行改进设计,使其在保证着陆机构承载能力的同时有效减轻重量;优化结果通过序列规划方法而非人工修改迭代设计得到,能够保证结果的有效性。相比于传统盘绕式伸展臂,提升了抗弯性能,且在着陆阶段保证着陆机构能够承受着陆冲击,实现探测器的安全着陆。
