Abstract : The Korea Aerospace Research Institute plans to launch a lunar module by 2025, and so is carrying out a preliminary study.
Landing stability on the lunar surface is a key design factor of a lunar module. In this paper, a 1/6 scale model of a lunar
module is investigated, for its landing stability on non-level surfaces. The lunar module has four tripod legs, with aluminum
honeycomb shock absorbers in each leg strut. ADAMSTM, the most widely used multi-body dynamics and motion analysis
software, is used to simulate the module¡¯s lunar landing. Three types of dampers in the struts (rigid, viscous, and aluminum
honeycomb dampers), and two types of lunar surfaces (rigid and elastic) are considered. The Sforce function is adopted, to
model the aluminum honeycomb dampers. Details on the modeling and analysis of the landing stability of the 1/6 scale lunar
module and the simulation results are provided in this paper.
