Based on ADAMS mechanical simulation software, a microgravity environment was established by computer and some simulation study had been carried out about the lunar lander.

By simulating analysis, the optimal parameters, Numbers and type of construction machinery can be obtained, and the smallest cost and shortest period of construction projects can be predicted.

In the process of completing, the mechanism design requests are considered fully, some methods such as the computer assistant simulation design, finite element analysis and test verify are adopted.
