摘要
文章提出了一种适用于无人自主作业的月球采样器的摆杆式展开机构,通过数值仿真分析及试验对该机构在月球低重力场下展开过程中的动力学特性进行了研究,研究结果的对比验证了该展开机构设计的可行性,并提出了优化方案。
An unfolding mechanism for the unmanned automatic lunar soil sampler are presented in the paper. Numerical simulations and experiments are employed to study the dynamical characteristics of the unfolding process under the lunar gravity. By comparing the results of two different methods, the feasibility of the design is verified, and some optimization plans are proposed.
