| Abstract: |
| This paper introduces the composition of landing gear of chang’e -5 Lunar Explorer, the precise assembly method of key components, and the precise assembly method of whole machine. By selecting high-precision assembly datum and designing special assembly tools for loading and holding force, the problems of weak rigidity and poor stability of bellows are solved and the high-precision assembly of main pillar bellows and aluminum honeycomb are realized. Through the radial alignment assembly method of large size spring, the problems of stagnation and large resistance in the expansion of multifunctional auxiliary pillar were solved. By reasonably formulating the integrated assembly process route and optimizing the assembly path, the high-precision locking and unfolding of the landing gear are realized. |
