Reliability design for the landing gear of Chang'E-3 probe

Landing gear is one of the important components of Chang'E-3 Probe. The device was used to absorb the impact energy of Chang'E-3 Probe during the landing process. After landing on the moon, it can support the lander steadily for a long time. In order to assure the reliability of the landing gear and deal with the extremely severe landing conditions, many reliability measures were adopted in the design procedure, such as selection of cushion materials, optimization of mechanism configuration, design of deployment mode, allocation of buffer force and control of its variation. The successful landing on the moon of Chang'E-3 Probe has completely verified the high reliability of the landing gear.
