Fig. 11.17 Typical model of landing site and the lunar lander
Fig. 11.18 Finite element model for analysis of landing impact dynamics
landing impact characteristics. Therefore, based on theory of transient dynamics, the
finite element model of landing gear mechanism (as shown in Fig. 11.18) was built
with mature commercial software like MSC and Patran Dytran to verify design of
the landing gear mechanism. Different landing process was simulated according to
landing condition and lunar terrain of landing site, so as to improve design and guide
ground landing impact test.
