It is necessary to investigate the lunar lander soft-landing by considering the flexible body and legs because the impact of deformation is significant. There is a new method for research on landing impact performance in this paper. Firstly a dynamical model of 1/4 lunar lander with four suspension legs is build and simplified. After getting oscillation equation of the model, founds two simulation...
Landing dynamics analysis is necessary for the success of the lunar lander soft-landing. Recent advances in computational speed have made lunar lander soft-landing modeling and simulation using a nonlinear, transient dynamics, finite element analysis code more feasible. A new approach to study the soft-landing of lunar lander has been described in this paper. The simulation of lunar lander soft-landing...
The influence of flexible body and legs of lander, plastic deformation of lunar regolith on landing impact performance of lander is rarely researched, and literatures about using transient dynamics to analysis soft landing impact performance of lunar lander are also less. In this paper, a new idea and method for research on landing impact performance is presented. Flexible models and transient dynamics...
